♦ KNOAVLEDGE * 



[Sept. 2G, 1884. 



sitafe, occupy for tbe fragments of any 8inf,'lo body (which must have 

 solidified before disruption) to diverge into such wholly different 

 orbits as those described by the planetoids, the very wide 

 scattering of their nodes, and their sorting into separate 

 groups, and invite you to study what Sir William Thomson 

 says as to the limits of the antiquity of our solar system. For- 

 give me for saying that you seem to resent the assumption that 

 Olbers was wrong, as though yon wish to make a personal quarrel 

 of the matter! If you insist on believing that the 2.50 known 

 (and X undiscovered) bodies travelling between Mars and Jupiter 

 in such very diverse orbits, are fragments of one large one, I am 

 not concerned to undeceive you. — C. E. Doyle. The "Notes on 

 Mapping" will be resumed later on. There is a great press of 

 matter on our columns just now. — Telegraphist. The series of 

 articles on electrical measurement did not cease where you imagine, 

 but was continued into Nos. 75 and 77 ; and the articles, so far as 

 they went, were complete. The interest and importance attaching 

 to the subject are certainly great, and Mr. Slingo will probably 

 further augment the series at an early date ; at least we hope space 

 will permit him to do so.

Carlton Chess Club, 12, Bell-street, Edgware-road. 

 Sir,— Being desirous (jf having a Chess club under the above 

 name, we should be glad if you would help us by giving us a few 

 simple rules and hints as to how it should be conducted, and how 

 we should proceed when challenging another club. Can you tell ii'- 

 the names of any minor Chess clubs we could play for a start ? Vn- 

 have several very good players. Caelton C. C. 



[Elect committee and officers, draw up the usual rules, or copy 

 those of the City of London Chess Club, which you may get on 

 application. Having formed the club, arrange a handicap tourna- 

 ment for the winter season, in which, if the number be not too 

 large, each player (properly handicapped) plays one game witli 

 every other man. As to inter-club matches, there has been a 

 meeting of the secretaries of London C. C. this week, at the Ludgate 

 Circus C. C, at Oliphant's Cafe in St. Bride-street, for the purpose 

 of settling matches for this season, but we have no doubt that :» 

 written or personal application to the secretary will give you any 

 particulars you may require. The nearest club in your neighbour- 

 hood is the C. C. of the Railway Clearing-house in Seymour- 

 street. Perhaps, though rather strong, they might accept a 

 challenge. Any further information as to conduct of a club you 

 will, no doubt, obtain from the courteous secretarj' of the City of 

 London C.C., Newgate-street, E.C. If you wish your Club to 

 prosper, give it as much publicity as you can by sending notices of 

 your doings to the press. We understand that a new weekly paper 

 — the WeeMy Echo — will shortly be started with a Chess Column, 

 a part of which will be especiallj- devoted to the London Clubs.— 

 Mephisto.]

 decisive. 



J. K. Milne. — Ton are mistaken about the rule of Pawn takes 

 Pawn in passing. Supposing — 



mm 



In this position the white Pawn moves two squares. Then thp 

 black Pawn has the right to take the white Pawn, as if the latter 

 had only moved one square. But if the position is like this : — ■ 



then the white Pawn can advance two squares, and the black 

 Pawn has no right of taking the white Pawn.
