we regret to ay is not always employed 

 in the scientific world. One of these a 

 proposition in Simpson's Geometry, which 

 has been for upwards of seventy years re- 

 ceived as genuine, and adopted by more 

 modern geometers, we may venture to 

 particularize. If two triangles have one 

 angle in the one equal to one angle in the 

 other, and the sides about either of the 

 other angles proportional, then will the 

 triangles be equi-angular, provided these 

 last angles be either both less or both 

 greater than right angles. This is most 

 satisfactorily proved to be false. We con- 

 clude with saying, that we have never 

 seen a work so admirably calculated to 

 accomplish the purpose for which it was 

 designed to supply all the wants of the 

 student in geometry with the least expen- 

 diture of time, and, in a manner, free from 

 ambiguity, vigorous and elegant. 



Ursino, Dr. G. P.. Logarithm! vi. De- 

 cimalium scilicet numerorum ab 1 ad 

 100,000 et sinuum et Tangentium ad 10", 

 4-c. tfc. ffc. Christiana. When we first 

 saw these tables, we were at a loss to 

 conceive the use of publishing a set ex- 

 tending only to 100,000, and to six places 

 of decimals. A closer inspection has con- 

 vinced us that, from the extreme accuracy 

 with which they are printed, there are 

 none so well adapted for general pur- 

 poses ; while, in the clearness and size of 

 the type, they possess a recommendation 

 which can be appreciated by those alone 

 who are familiar with logarithmic calcula- 

 tions. While Mr. Babbage's Tables are 

 requisite for all the more delicate investi- 

 gations of science, we shall expect to see 

 those of Ursinus employed in all the nu- 

 merical operations of ordinary life. 



PROCEEDINGS OF LEARNED SOCIETIES. 



DOM ESTI C. 

 BOYAL SOCIETY. 



May 17. W. H. White, Esq. was ejected 

 from the society. A paper was read, on 

 the secondary deflection produced in a mag- 

 netized needle by an iron shell, in conse- 

 quence of an unequal distribution of mag- 

 netism in its two branches, discovered by 

 Captain Wilson, by P. Barlow, Esq." Also 

 another, " on the difference of meridians of 

 the royal observatories of Greenwich and 

 Paris, by T. Henderson, Esq." This gentle- 

 man has detected an error of one second, 

 committed at Greenwich, in the reduction 

 of the observations made officially for deter- 

 mining the differences of longitude of these 

 two places, which amounts, in all probabi- 

 lity, to 9'-21"-5. A letter was read from Mr. 

 Rumker of Paramatta, giving an account of 

 several series of observations made at the ob- 

 servatory there. 24. The Right Hon. C. 

 W.W.Wynne was elected into the society; 

 and a paper read, " on destroying the fire- 

 damp in mines by the chloride of lime, by F. 

 Fincham, Esq., by sprinkling the chloride of 

 lime in places where the fire-damp had ga- 

 thered." This gentleman has succeeded in 

 rendering part of Bradford colliery, where ex- 

 plosions were frequently taking place, ex- 

 empt from danger. A paper was also read, 

 " on some properties of heat, by R. W. Fox, 

 Esq." 31. E. W. Pendarves, Esq., M. P. ; 

 Lieut.-Col. Miller ; Major-Gen. Wavell, and 

 Dr. Harwood were admitted members of the 

 society. A paper was communicated, tS on 

 the resistance of fluids to bodies passing 

 through them, by J. Walker, Esq." Also, 

 "corrections of the pendulum depending on 

 Uie value of the divisions of the level of the 

 small repeating circle, as recently ascertained 

 by the experiments of Captain Skater, by 

 Captain E. Sabine." Also a paper, ' on the 

 effect produced on the air-cells of the lungs 



when the circulation is too much increased, 

 by Sir E. Home." June 16. W.J. Guthrie, 

 Esq., was admitted a fellow ; and a paper 

 read, " on the ultimate composition of sim- 

 ple alimentary substances, with some preli- 

 minary remarks on the the analysis of or- 

 ganized bodies in general, by Dr. Prout." 



FOREIGN. 

 INSTITUTE ACADEMY OF SCIENCES. 



May 21. -A favourable report was deli- 

 vered by M. M. de Prony, Molard, and Gi- 

 rard, on a model of a carriage with a move- 

 able pole, invented by M. Van Hooricb, and 

 on which principle several coaches are now 

 being constructed for the public conveyance. 

 M. Arago communicated a memoir of Mr. 

 Cowper, Professor at Kasan, on different 

 questions relative to the magnetism of the 

 globe. M. Giron de Buzareingues, a cor- 

 respondent, read a memoir, entitled " Ex- 

 periments and Observations on the Repro- 

 duction of Domestic Animals." A botanical 

 communication was received from M. Bro- 

 get, naturalist at the Isle of France. 28. 

 M. M. Gay Lussa, and Thenard reported 

 on a memoir of M. Pol ydore Bo ullay, con- 

 cerning the double iodures which is to be in- 

 serted in the collection of papers by persons 

 who are not members. M. M. Thenard and 

 Chevreul reported on a memoir of M. Bo- 

 nastie on a combination of the volatile oils. 

 This gentleman was recommended to con- 

 tinue his labours. June 4. M. Arago read 

 an extract from a letter of M. Brunei to M. 

 Delessart, relative to the proceedings in the 

 tunnel under the Thames. M. Cagnard de 

 Latour read a note on the two kinds of vibra- 

 tion of the artificial glottis. 11. The annual 

 meeting for the distribution of prizes was 

 held this day ; when the mathematical prize 

 was awarded to M. M. Colladon and Sturen 

 of Geneva. La Lande's astronomical prize
