534. Scientific Intelligence. 



This little volume contains a republication in English of the 

 writings of an author, Dr. John Mayow, who, although he died 

 in 1679 at the early age of 36, made most important contributions 

 to the subjects of Chemistry and Physiology. These had been 

 long forgotten, when Dr. Thomas Beddoes in 1790 brought them 

 to notice in his Analyses of Mayow's Chemical Theories. The 

 five treatises which constitute the Opera* omnia of Mayow are 

 now presented entire, and this book hence has a peculiar value to 

 all interested in the history of Chemistry. 



9. Graphic Algebra; by Arthur Schultze, Ph.D., New 

 York University (The Macmillan Co.). — This volume follows the 

 author's larger works on elementary algebra and advanced 

 algebra, and presents in very clear form the process of drawing 

 the graph of a function of one variable ; from this are deduced 

 the most practically convenient methods of solving quadratic, 

 cubic and biquadratic equations by means of a standard curve 

 combined with straight lines and circles. With the exception of 

 two these methods are original with the author, who first pub- 

 lished them in a paper read before the American Mathematical 

 Society in 1905. The book leaves little to be desired in the 

 way of economy and efficiency, its aim being to replace compu- 

 tation by measurement in solutions where a high degree of accu- 

 racy is unnecessary. w. b. 



10. Ostwald's Klassiker der Exakten Wissenschaften. Leip- 

 zig, 1907 (Wilhelm Engelmann). — The following are the latest 

 additions to this important series : 



No. 160. Untersuchungen liber die Galvanische Leitfahigkeit 

 der Elektrolyte, von Svante Arrhenius. Tjbersetzt von Anna 

 Hamburger und herausgegeben von Otto Sackur. Pp. 153, 

 mit 6 Figuren im Text. 



No'. 161. Abhandlungen von Christian Doppler. Heraus- 

 gegeben von H. A. Lorentz. Pp. 194, mit 36 Figuren im Text. 



11. Decapod Crustacea of the Bermudas, Part I. JBrachyura 

 and Anomura ; by Addison E. Verrill. Trans. Conn. Acad. 

 Science, vol. xiii, pp. -299—174, plates ix-xxviii, Jan. -May, 1908. — 

 This report includes a review of all the known species and sub- 

 species (78) with accounts of their distribution and habits, and 

 full descriptions of many species. Nearly all the species are 

 illustrated by half-tones from photographs. There are included 

 16 additions to the Bermuda fauna, and 9 are described as new 

 species or subspecies. One, which is made the type of a new 

 genus and species, Troglocarcinus corcdllcola. of the family 

 Hapalocarcinidae, forms dens or houses under the surface of liv- 

 ing corals [3fussa and Mceandra). For this group of peculiar 

 small crabs, all of which are parasitic in corals, the new super- 

 family, Hapalocarcinidea, is proposed. This article includes a 

 pretty full bibliography and index to scientific names.
