There were three RFC's published during the month of April, 1994 (all on April first): RFC St WG Title ------- -- -------- ------------------------------------- RFC1605 I (none) SONET to Sonnet Translation RFC1606 I (none) A Historical Perspective On The Usage Of IP Version 9 RFC1607 I (none) A VIEW FROM THE 21ST CENTURY St(atus): ( S) Internet Standard (PS) Proposed Standard (DS) Draft Standard ( E) Experimental ( I) Informational Steve Coya (scoya@nri.reston.va.us) Cooper [Page 7] Internet Monthly Report April 1994 INTERNET PROJECTS ----------------- ANSNET/NSFNET BACKBONE ENGINEERING ---------------------------------- Network Status Summary ====================== ANSnet total packet traffic grew by over 5% in April '94. The process of CIDR aggregation continued in April. A decrease in the ANSnet forwarding table growth was observed (1.72%) for the month due to the withdrawal of 2,954 class based destinations. April Backbone Traffic Statistics ================================= The total inbound packet count for the ANSnet (measured using SNMP interface counters) was 58,015,017,839 on T3 ENSS interfaces, up 2.03% from March. The total packet count into the network including all ENSS serial interfaces was 68,132,330,845 up 4.99% from March. Router Forwarding Table Statistics ================================== The maximum number of destinations announced to the ANSnet during April was 19,721 up 1.72% from March. This decrease in the monthly forwarding table growth rate is attributed to CIDR aggregation. The number of network destinations configured for announcement to the ANSnet but were never announced (silent nets) during April was 10,558. BGP-4/CIDR Deployment Status =========================== The following autonomous systems are currently exchanging routing information with ANSnet via the BGP-4 protocol: 3 MIT 22 NOSC 86 SURANet 101 NorthWestNet 114 SESQUINet 185 MERIT-OFFNET 195 SDSC 200 BARRNet Cooper [Page 8] Internet Monthly Report April 1994 204 PSCNet 237 MichNet 266 CICNet 267 CICNet 279 SURANet 293 ESNet 297 NASA 372 NASA 560 NEARNet 577 CA*Net 600 OARNet 685 NorthWestNet 701 AlterNet 771 NASA 1133 Dante 1206 PSCNet 1225 CICNet 1240 ICMNet 1263 NASA (test) 1321 ANS (San Francisco) 1322 ANS (Los Angeles) 1323 ANS (Chicago) 1324 ANS (New York) 1325 ANS (Cleveland) 1326 ANS (Hartford) 1327 ANS (Washington DC) 1328 ANS (Houston) 1329 ANS (Greensboro) 1330 ANS (St. Louis) 1331 ANS (Seattle) 1332 ANS (Denver) 1333 ANS (Atlanta) 1670 ANS (test) 1674 Dante 1681 ANS (Ann Arbor) 1740 CERFNet 1800 ICMNet 1838 CERFNet 1879 EUROPE-RS 1957 ANS-CIX 2002 IBM Packet Video 2149 PSINet 2548 Digital Express 2551 Netcom 2882 COREN-ONE 3354 THENet 9010 ANS (test) Cooper [Page 9] Internet Monthly Report April 1994 As of early May '94, we have observed the withdrawal of 2,954 class based destinations from the ANSnet router forwarding tables that are now represented by 435 configured aggregates. Among these 37 configured aggregates: 398 of these are top-level aggregates (not nested in another aggregate). 184 of these are actively announced to ANSnet. 162 of these have at least one subnet configured (the other 22 may be saving the Internet future subnet announcements). 142 of these have resulted in the withdrawal of at least one configured more specific route. 136 of these have resulted in the withdrawal of 50% of their configured more specific routes. 116 of these have resulted in the withdrawal of most (80%+) of their more specific routes. For further details on these CIDR aggregates, see merit.edu:pub/nsfnet/cidr/nestings.announced for full listings. Other gated software changes will be deployed over the next couple of months to improve policy processing (required to support some advanced forms of proxy aggregation). Routing Stability Measured on the T3 Network ============================================ The three different routing stability measurements that have been reported on over the past year were based on rcp_routed log file entries. Gated software was deployed at the end of February to replace rcp_routed. These routing stability reports have not yet been converted to use gated logging. No data is available for the month of April. Data collection is expected to resume shortly. Notable Outages for April '94 ============================= E134 (Boston) suffered an extended outage due to hardware problems on 04/02. E136 (College Park) suffered an extended outage due to software problems on 04/04. Cooper [Page 10] Internet Monthly Report April 1994 E137 (Princeton) was unreachable via T3 due to hardware problems on 04/06. E172 (Phillips Labs) suffered an extended outage due to power problems on 04/12. E181 (WLN) was down for an extended time due to site move on 04/13. E137 (Princeton) was unreachable via T3 due to hardware problems on 04/17. UNAM suffered an extended circuit outage on 04/24. E173 (ITESM) and UNAM suffered extended circuit outages on 04/28.

No.3, April 1994 Editor: Josefien Bersee __________________________________________________________________ * DANTE SHAREHOLDING EXPANDED * On 25 March 1994, the DANTE Shareholders meeting took place in Amsterdam. At the meeting the ownership of the company was formally transferred from RARE to the Shareholders. RARE had been the legal owner and only shareholder of DANTE in the first year of its existence. During the meeting RARE was formally discharged of all responsibility for the company, with the new Shareholders acknowledging RARE's important role in setting it up. The chairman thanked RARE for its support. When issuing the Shareholder Certificates to the organisations which had signed the final Shareholders Agreement the company secretary, Boudewijn Nederkoorn from SURFnet, said: "This is an historic occasion which marks a major step forward in pan-European service provision for the research community". Cooper [Page 11] Internet Monthly Report April 1994 The following persons were appointed on the new Board of Directors: Klaus Ullmann (DFN, DE) as a Director for a period of three years and as Chairman of the Board; Boudewijn Nederkoorn (SURFnet, NL) and Fernando Liello (CNUCE, IT) as Directors for a period of three years, and Juergen Harms (SWITCH, CH) as a Director for a period of two years. The new Board will make a proposal for a fifth Director, who is to be approved by the Shareholders. The Operational Unit Steering Committee, which was originally set up by potential shareholders of DANTE to manage the creation of the company, will be wound up as it has now completed its task. The organisations which had signed the Shareholders Agreement at the time of the meeting were: SWITCH (Switzerland), DFN (Germany), HUNGARNET (Hungary), CNUCE (Italy), SURFnet (Netherlands), NORDUnet (Nordic countries), FCCN (Portugal), ARNES (Slovenia), HEFC(E) (on behalf of the UK). Organisations from other countries, including Belgium, Spain and Greece, which had been unable to sign the Agreement before the meeting, are still expected to do so. * EuropaNET: THE LATEST DEVELOPMENTS * In co-operation with CEENet, the Central and Eastern European Networking Association set up in January 1994, DANTE has prepared a plan for the development of international connectivity in Central and Eastern Europe. The plan takes account of the financial and other support that is likely to be available from ACOnet, NORDUnet and the CEC's PHARE Programme. Implementation of the plan, which outlines general principles as well as details for individual countries, would represent a significant step forwards. DANTE has offered to set up all the interconnections which include EuropaNET if the plan goes ahead. The document is available from the DANTE gopher server (EuropaNET directory). The 2 Mbps line between Amsterdam and Washington (finally) came into operation on 17 March 1994. Dai Davies, DANTE general manager, commented: "This was an unusually challenging activity and the effort required from DANTE to do so is a sad reflection on the difficulties that still exist in getting international line providers to organise simple things." The line was ordered in November 1993 and was originally planned to be operational by January 1994. Since the beginning of April, EuropaNET is capable of exchanging routing information with its peers on the basis of the new version of the Border-Gateway-Protocol (BGP-4). Version 3 of the protocol does not support Classless Interdomain Routing (CIDR), which offers routers the possibility to aggregate routing entries. As routing tables in the Internet were becoming too big to be handled within a Cooper [Page 12] Internet Monthly Report April 1994 router, there was an urgent need to migrate to BGP-4. * CALL FOR TENDER MailFLOW * An open Call for Tender for the provision MHS-Coordination, MailFLOW, has been issued by DANTE. MailFLOW is currently provided on behalf of DANTE by SWITCH, the Swiss research network. The purpose of the tender is twofold: on the one hand to give other providers a chance to step forward and on the other hand to introduce a competitive element in the Service provision. Tender requirements are available from the DANTE gopher server, in the MailFLOW directory (under Applications Services). The deadline for submitting proposals is 30 June 1994. * HIGH SPEED PROGRESS * As reported in the previous "Works", in January DANTE secured approval in principle from the EuroCAIRN (European Co-operation for Academic and Industrial Research Networking, a EUREKA Project) Project Board for a proposal to produce a study report, the target of which is to specify information and requirements necessary to support funding proposals and the formal procurement of a high- speed backbone. EuroCAIRN now has enough financial commitments to pay for the proposed study report. Preliminary contract negotiations have already started with the CEC. DANTE is prepared to start work immediately following the next EuroCAIRN meeting if a contract is approved. * DISCUS, NEW NAME FOR A FAMILIAR SERVICE * Last month CONCISE, the information server set up as part of the COSINE project, was renamed DISCUS. A new name has been introduced to mark the beginning of a new period: in 1994 Level-7 will be providing the service on behalf of DANTE. The main issue in the Information Services area is to define which role DANTE should play in offering pan-European information services which are not yet available from other sources (and which would be commercially viable). In parallel, the future possibilities of DISCUS will be addressed. * DANTE GOPHER INSTALLED * A first set of information on the company, staff and services is now electronically available from the DANTE gopher server Cooper [Page 13] Internet Monthly Report April 1994 , see "Information on DANTE and its activities". An important future aim of the information server is to present on a regular basis a range of relevant statistics relating to EuropaNET. DANTE is currently looking into the definition and production of such statistics. * EuropaNET POSTER AVAILABLE FROM DANTE * A full-colour poster of the EuropaNET network is now available and can be obtained by sending a message to DANTE (dante@dante.org.uk). __________________________________________________________________ DANTE - Lockton House - Clarendon Road - Cambridge - CB2 2BH - UK tel +44 223 302992 fax +44 223 303005 e-mail dante@dante.org.uk __________________________________________________________________ Josefien Bersee DANTE Publicity Manager INTERNIC -------- INFORMATION SERVICES Contact Information: Reference Desk Information Toll-free hotline +1 800 444-4345 email info@internic.net Fax +1 619 455-4640 InterNIC Suggestions or Complaints Suggestions suggestions@internic.net Complaints complaints@internic.net NICLink Information info@is.internic.net NSF Network News newsletter subscriptions newsletter-request@internic.net newsletter comments newsletter-comments@internic.net InterNIC Seminar Series seminars@internic.net or +1 800 444-4345 Cooper [Page 14] Internet Monthly Report April 1994 Listserv lists net-happenings listserv@internic.net net-resources listserv@is.internic.net nics listserv@is.internic.net InfoGuide Host Name is.internic.net Host Address 192.153.156.15 Postal address InterNIC Information Services General Atomics P.O.

To that end we shall bitmap display and camera, and control them via remote procedure calls (RPCs). High Performance RPC Because a network dedicated device has direct access to its own network output buffer memory, it can create a stencil of the packets that it sends within that memory and be assured that this stencil will not overwritten. The task of sending successive RPC messages for the display process consists of changing only those locations in the stencil that are altered from call to call. These are: (1) Destination addresses, in LAN and IP headers (2) Source and destination UDP ports in the UDP header (3) Packet lengths, in LAN and IP headers (4) Checksums, in LAN and IP header (5) Procedure and program indexes, in the RPC header and finally, (6) Supply procedure arguments at the end of the stencil We showed at the end of March that the techniques developed for high- performance RPC based upon this technique produced a level of performance at least ten times greater that that offered by the standard UNIX stack in a SPARCstation-10. Cooper [Page 18] Internet Monthly Report April 1994 We expect that performance obtained in the specialized display and camera devices that we are building will perform at least as well, and probably, substantially better. A question arises. At what level does the interface to a 'remote' display belong? This project postulates that the coming advances in VLSI, when combined with gigabit LAN performance, allow that interface to be made very low. We are replacing the system bus with a gigabit network. Thus we should interface to the display much lower than the level used in the X-windows interface. An approach which is being considered seriously is to rewrite the device dependent portion of the X-windows server code. In particular, to rewrite the Pixblit code, so that its rasterop procedure calls are transformed into RPCs that are sent across the ATOMIC network to the display device for execution. In this approach, no windowing system assumed by the network display device whatsoever. The display is only required to implement a battery of RPCs. The virtual interface presented to the network will initially be a very simple one. Subsequent to this, experimentation with multiple JPEG streams will occur. JPEG data may not use an RPC model for data delivery. This remains to be determined. At a later stage it will be necessary to implement security and access restrictions to the display device. Display Network Virtual Device Bruce Parham, an EE formerly with Jet Propulsion Laboratory, was hired to design the display and camera network virtual devices. The broad design outlines are to develop a display that allows two JPEG streams plus device and raster graphics commands to arrive over an ATOMIC gigabit LAN port. The display should be capable of rendering two NTSC video windows in real-time. To achieve this the display will include a LANai gigabit network interface, a graphics DSP, and JPEG chips. The design of a 1280x1024 24-bit color CRT display is held hostage by the pixel rate. Modern computer CRT displays are progressively scanned. Human factors engineering decrees that refresh rate must be at least 60 frame/sec. Currently, a rate somewhat higher, in the low 70s, is favored to eliminate all trace of image flicker. A rate of 72 frame/sec results in a pixel rate of approximately 90 Mpels/sec, or 11 ns/pel. Cooper [Page 19] Internet Monthly Report April 1994 The principal design problem is therefore one of memory organization. If it is desired to allow the frame buffer to be updated by real-time video sources, the frame buffer memory bandwidth must approximate twice that required by refresh. An analysis of available memory parts and organizations is underway to determine what the most cost effective current engineering solution to this is. Previously, a good choice for the video DSP would have been the TMS 32040 from Texas Instruments, which contained a video/VRAM refresh controller and a graphics-oriented CPU. Unfortunately, within the last month it has been withdrawn from support. Its replacement is the TMS320C8x. This is a multi-DSP 2 GOPs processing chip that is designed to carry out JPEG or MPEG-II decode in real-time. At $1500/part and not yet truly available, it is tantalizing, but inappropriate. This is primarily because it does not come with publicly available JPEG/MPEG. The programming resources required to embed those algorithms is outside the current scope of the NAAAN contract. This is an issue that deserves some consideration at a higher level. If this is indeed a appropriately powerful, fixing on a standard DSP/video chip, and making publicly available a standard suite of JPEG/MPEG software for it, could speed the spread of HDS hardware development and so its applications. We have decided to replace the TMS 34020 with two chips: A TMS 320C40 (which is a similarly numbered chip - but quite different internally) and a graphics controller chip that is yet to be determined. The 320C40 is a super-scalar DSP with dual-bus support. It promises to be endlessly fascinating to program, that is, if we can ever figure out why we need to use parallel multiply/add/index instructions. Seriously though, its dual-bus support provides a Harvard architecture, allowing dedication of one bus to data transfer. That bus will be used largely to transfer network packets in/out of 320C40 memory, provide compressed JPEG input to the CL560 chip FIFOs, and to perform frame-buffer rasterop update. Details of the display design will be made available in subsequent reports.

MichNet affiliate organizations now number 85, in addition to the 11 member universities. Cooper [Page 24] Internet Monthly Report April 1994 Merit Network's MichNet Seminar, enthusiastically received by member and affiliate organizations at its introduction in Ann Arbor in late February, will be offered on the campus of Central Michigan University in Mt. Pleasant on 19 May. Designed primarily with new affiliate needs in mind, topics include an overview of the Internet; MichNet and Merit Services; Merit's Cruise of the Internet; and Internet tools, including FTP, Gopher and WWW. Merit held a series of Internet Briefings and Open Houses for Michigan's K-12 communities in March and April. The eight, day- long Internet Briefings hosted throughout the state by MichNet member and affiliate institutions, were planned to familiarize teachers and administrators with the benefits of direct Internet access and to provide details on new funding opportunities. With the settlement of the "Michigan Bell Rebate Case," more than $26 million is available for educational telecommunications projects. The governor-appointed Michigan Council on Telecommunications Services for Public Education issued a "Request for Pre-Proposal," inviting proposals for allocating approximately $9 million of the total funds, and encouraging collaborative efforts between groups of organizations. Merit's increased K-12 outreach initiatives were designed to help schools respond to the "Request for Pre-Proposal," enhancing the opportunity to expand programs already developed in partnership with the Michigan schools. Merit is working with the Society of Manufacturing Engineers (SME) on the Cooperative Network for Dual Use Information Technologies (CoNDUIT) project. Funded by a $24.3 million Technology Reinvestment Program grant, the new program aims to provide small manufacturing businesses with training using network infrastructure. CoNDUIT will develop a network that will allow full implementation of teleconferencing, remote library access, and daily communication among business and educational facilities. A central resource for the network will be an Industry NIC (I-NIC), providing business with human and online support systems for understanding and using network technologies. Multi-media training will be a significant I-NIC offering. Merit is also participating in the Michigan Industrial Extension Partnership, a 1993 TRP award made to Michigan State University to provide network services to industrial extension agents in the state. Jo Ann Ward (jaw@merit.edu) Merit Network, Inc. Information Services Cooper [Page 25] Internet Monthly Report April 1994 MERIT/NSFNET ENGINEERING ------------------------ The report summarizes recent activities of Merit's NSFNET Project Internet Engineering and Network Management groups. Routing Registry ---------------- Merit is happy to announce the Merit Routing Registry. Whereas Merit designed and manages the PRDB (Policy Routing Data Base) for the NSFNET service, RIPE pioneered a policy routing registry for the European community. The RIPE Routing Registry is based on the document, RIPE-81. With RIPE's collaboration, Merit installed RIPE-81 software and then extended the policy descriptions in order to realize more complex policies. The Merit Routing Registry will be a companion registry to the RIPE Routing Registry and is intended to serve the community that is not served by RIPE. This is a new service and we consider ourselves still in the beta phase. Registrations may be basic policy descriptions defined in RIPE-81 or complex routing policy descriptions defined in the Extended Policy Syntax document by Chen, Gerich, Joncheray, and Yu. The Extended Policy Syntax document may be found on rrdb.merit.edu:pub/meritrr/policy_syntax.txt. Documentation for using the MeritRR can be found on rrdb.merit.edu:pub/meritrr. Merit and RIPE anticipate that the combined registries will provide a more comprehensive picture of the routing interactions in the Internet. We are working together to allow the two registries to appear like one virtual registry to the various tools that are developed. We welcome your comments on all aspects of this project. For more information, please respond to rradmin@rrdb.merit.edu. Several new tools are also available for anonymous ftp from rrdb.merit.edu:/pub/meritrr and include: -astrace.tar.Z: The new prtraceroute to use with the NARR registry -aggrwalk.tar.Z: A tool to expand aggregates into sub components -alc.tar.Z: The Routing Policy Server code Policy Routing Data Base ------------------------ Several enhancements have been made to the Policy Routing Data Base (PRDB). These include: Cooper [Page 26] Internet Monthly Report April 1994 - "Fake ASs" are no longer required for peers which need attach to AS690 in more than one place. A new syntax "metric:AS(NSS)" has been created to support this, for use in the PRDB AS-metric lists. All PRDB reports (including whois and ftpable reports) will soon include this syntax; it will soon be accepted on NACRs as well. - A new "NOCONFIG" option has been added. This option allows nets to be registered in the PRDB without passing knowledge of those specific nets on to the Gated config files and the backbone routers. The initial use of this feature has been to suppress the configuration of more-specific-subnets of announced aggregates. - The "whois -h prdb.merit.edu 'aggchk '" command has been modified to include information about whether the aggregates and their more-specific subnets are being announced. Flags in the left of the report mark currently-announced nets with "+", never-announced nets with " ", and nets that have been withdrawn N days ago with a the number N. Nets which have had the "NOCONFIGURE" option are marked with the flag "U"; Proxy nets are marked with "P". - Two new temporary reports are available on merit.edu:pub/nsfnet/cidr. "nestings.announced" lists all aggregates registered in the PRDB, along with their more- specific-subnets and their offnet status (see above). "cidr_savings" gives a summary of the same information by aggregate. - Proxy aggregation at a single ENSS is currently supported in the PRDB; final testing of the feature is awaiting deployment of GateD Proxy code. - A new "flags" field has been added to the output of "whois -h prdb.merit.edu ". This "flags" field shows the status of the "NOCONFIG" and "Proxy" flags, and will hold future flag values. CIDR Progress ------------- IE staff are working with the remaining non-CIDR compatible NSFNET regional networks to upgrade to BGP4, to begin announcing CIDR aggregates, and to withdraw specific routes covered by those aggregates. The approximately 18,450 routes currently announced include 276 aggregates and 3,275 more specific routes have been withdrawn from routing announcement. Merit's offnet reports Cooper [Page 27] Internet Monthly Report April 1994 provide a historical data series that since April includes the impact of specific network announcement withdrawals. The data is available for anonymous ftp from merit.edu:~ftp/pub/nsfnet/offnet/ with postscript files of the charted data have names in the format: Month1.ps, Month2.ps, and two files with cumulative table data named "r_tab" and "path." IDRP Project ------------ Continued development and testing have followed release of version 1.0 of the IDRP software. Merit's Inter-Domain Routing Policy Project for the US-FAA is an implementation of OSI-IDRP for gated. A generic PATRICIA trie implementation supports multiple independent tries of several critical data structures including RDIs. The software is available for anonymous ftp from: merit.edu:pub/iso/idrp/faa/gated-idrp.0.9.6.tar.Z K-12 Domain Count ----------------- An analysis was performed for NSF on the number of K-12 names in the US domain. The listing of was prepared by walking the US DNS tree and is available for anonymous ftp from twain.merit.edu:pub/k12.uniq.Z Kenneth T.

Cooper [Page 30] Internet Monthly Report April 1994 The April USSC meeting focused on the continued improvement of NEARNET online information services. by NEARNET Client Services NORTHWESTNET ------------ In mid-April, the User Services group provided three Internet classes for 8 staff members from the King County Library System. They will take the information they have learned in these classes and apply it to the development of Internet services within their organization. The King County Library System serves over 40 sites in the Puget Sound region. This was also a busy month for the User Services Committee. On April 21, Jan Eveleth (director of User Services at NorthWestNet) moderated the monthly teleconference discussion, "Exploring Legal Issues on the Internet." As always, this topic produced spirited discussion. The following week, regional committee meetings were held at the Oregon Historical Society in Portland, Oregon and at The Evergreen State College in Olympia, Washington. The discussion topic, "Coping with Diversity," and agenda were duplicated at each meeting. Participants highlighted many areas in which diversity affects their work in supporting the Internet. Where diversity has created challenges, the group shared their ideas and experiences. Upcoming: The NorthWestNet training facility will open its doors for the first in a series of scheduled Internet classes in May and June. These for-fee classes are open to the public as well as NorthWestNet member organizations.

UCL ---- Replacement of the (10-30% lossy) Ethernet at ULCC by a Hub means that our International Internet Access is radically improved, especially for Mbone events. We helped Cambridge University to setup the mbone casting of their weekly saeminar series. Crowcroft proposed a modest modification to IP to meet the current IPng requirements, called I PING, that permits mutual use of routers by IP and IPng. It was proposed as a trivial strawman to measure and burn other proposals against, rather than a serious candidate. UCL Hosted the SIGCOMM 94 Program Committee meeting, whose deliberations will be forthcoming around now.

A gleam of pale sand, a whisper of deep flowing waters, and a farther glimmer of more sands beyond them challenged our advance. We had come to a "grapevine ferry." The scow was on the other side, the water too shoal for the horses to swim, and the bottom, most likely, quicksand. Out of the blackness of the opposite shore came a soft, high-pitched, quavering, long-drawn, smothered moan of woe, the call of that snivelling little sinner the screech-owl. Ferry murmured to me to answer it and I sent the same faint horror-stricken tremolo back. Again it came to us, from not farther than one might toss his cap, and I followed Ferry down to the water's edge. The grapevine guy swayed at our side, we heard the scow slide from the sands, and in a few moments, moved by two videttes, it touched our shore. Soon we were across, the two videttes riding with us, and beyond a sharp rise, in an old opening made by the swoop of a hurricane, we entered the silent unlighted bivouac of Ferry's scouts. Ferry got down and sat on the earth talking with Quinn, while the sergeants quietly roused the sleepers to horse. Plotinus is driven by this perplexity to reconsider the whole theory of Matter.477 He takes Aristotle¡¯s doctrine as the groundwork of his investigation. According to this, all existence is divided into Matter and Form. What we know of things¡ªin other words, the sum of their differential characteristics¡ªis their Form. Take away this, and the unknowable residuum is their Matter. Again, Matter is the vague indeterminate something out of which particular Forms are developed. The two are related as Possibility to Actuality, as the more generic to the more specific substance through every grade of classification and composition. Thus there are two Matters, the one sensible and the other intelligible. The former constitutes the common substratum of bodies, the other the common element of ideas.478 The general distinction between Matter and Form was originally suggested to Aristotle by Plato¡¯s remarks on the same subject; but he differs325 from his master in two important particulars. Plato, in his Timaeus, seems to identify Matter with space.479 So far, it is a much more positive conception than the ?λη of the Metaphysics. On the other hand, he constantly opposes it to reality as something non-existent; and he at least implies that it is opposed to absolute good as a principle of absolute evil.480 Thus while the Aristotelian world is formed by the development of Power into Actuality, the Platonic world is composed by the union of Being and not-Being, of the Same and the Different, of the One and the Many, of the Limit and the Unlimited, of Good and Evil, in varying proportions with each other. The Lawton woman had heard of an officer's family at Grant, which was in need of a cook, and had gone there. [See larger version] On the 8th of July an extraordinary Privy Council was summoned. All the members, of whatever party, were desired to attend, and many were the speculations as to the object of their meeting. The general notion was that it involved the continuing or the ending of the war. It turned out to be for the announcement of the king's intended marriage. The lady selected was Charlotte, the second sister of the Duke of Mecklenburg-Strelitz. Apart from the narrowness of her education, the young princess had a considerable amount of amiability, good sense, and domestic taste. These she shared with her intended husband, and whilst they made the royal couple always retiring, at the same time they caused them to give, during their lives, a moral air to their court. On the 8th of September Charlotte arrived at St. James's, and that afternoon the marriage took place, the ceremony being performed by the Archbishop of Canterbury. On the 22nd the coronation took place with the greatest splendour. Mother and girls were inconsolable, for each had something that they were sure "Si would like," and would "do him good," but they knew Josiah Klegg, Sr., well enough to understand what was the condition when he had once made up his mind. CHAPTER V. THE YOUNG RECRUITS Si proceeded to deftly construct a litter out of the two guns, with some sticks that he cut with a knife, and bound with pawpaw strips. His voice had sunk very low, almost to sweetness. A soft flurry of pink went over her face, and her eyelids drooped. Then suddenly she braced herself, pulled herself taut, grew combative again, though her voice shook. HoME²Ô¾®Ïè̫ʲôÐÇ×ù ENTER NUMBET 0016www.jiahei.com.cn
