Notices respecting New Boohs. 463 



sentence of § 116 is not sufficiently guarded to be accurate. In 

 Ex. 3, page 70, it is not stated what point S' is. On page 161 

 line 11, for "polar" read " poles." Two or three clerical errors 

 are easily corrected. The following historical one occurs on 

 page 78, Ex. 6 : " Mr. H. M. Taylor's paper was read before the 

 London Mathematical Society on Eeb. 14th, 1884," whereas he 

 had previously published his Note, " On a six-point circle con- 

 nected with a triangle," in the ' Messenger of Mathematics,' vol. xi. 

 (May 1881-April 1882). If we mistake not, the "circle" had 

 previously been given by him in a Trinity paper. In conclusion 

 we are glad to say that the text is not overburdened with corol- 

 laries and superfluous matter, the figures are excellent, and there 

 is a most judicious and varied selection of exercises. 



Revue Semestrielle des Publications Mathematiques redigee sous les 

 auspices cle la Societe Mathematique cV Amsterdam. Tome I., 

 l re partie. (Amsterdam. 1893. 104 pp.) 



The object which the Mathematical Society of Amsterdam has in 

 view in putting forth this Revue is " de faciliter l'efcude des sciences 

 mathematiques eu faisant connaitre, sans clelai de quelque import- 

 ance, le titre et le contenu principal des meraoires mathematiques 

 publies dans les principaux journaux scientifiques." Primarily it 

 is intended for the use of its own Members, but the Society has 

 rightly judged that such a publication, if well conducted, will be 

 of service to a much larger circle of readers. This opening number 

 contains titles of papers printed in about 120 journals, 19 of which 

 are British and 8 American. A careful list of the titles is drawn 

 up with various particulars of interest, (pp. 87-104). 



The title of each communication is preceded by a system of 

 notation adopted at the recent Congres International de Biblio- 

 graphie des Sciences Mathematiques, and is followed by a very 

 concise Compte-rendu of the contents. "We may say that the 

 Revue, though its objects are similar to those of the well-known 

 Fortschritte der Mathematik (Berlin), does not aim so high, for in 

 the generality of instances the insight into any paper given by the 

 notices here is little more than a student would infer from the bare 

 title. Its merit is that a much earlier record, if the editors keep 

 up to date, will be available for authors and readers. The papers 

 tabulated from this Journal are comprised in Vol. xxxiv. (Nos. 206- 

 209) and are seven in number. Two are given by the titles only : 

 of the others a fair abstract is given. Lord Eayleigh's papers are 

 assigned to "J. W. S. Eayleigh." We wish the Society good 

 success and a large clientele.
