cotangents, natural secants and cosecants, arcs, reciprocals, squares, 

 cubes, square roots, cube roots, circumferences, circular areas, spheri- 

 cal contents, powers, constants, hyperbolic logarithms, exponentials, 

 divisors, least divisors, interest tables, first nine multiples of numbers 

 up to i.ooo, with many auxiliary tables. The tables are designed to be 

 useful in computing, in the graphic method, in teaching arithmetic, and 

 also in the illustration of the theorems of algebra. The tables are mostly 

 four-place ; the}' have a uniform decimal arrangement similar to that of 

 seven-place logarithmic tables. They are mostly s3noptic, and are ar- 

 ranged so that the function mav be read oft' for any position of the deci- 

 mal point in the argument. 



Catalogue of Microscopes and Accessories. Bv W. H. Bulloch, 

 Chicago. S°, pp. 40. 



This catalogue is presented to the pul:)lic for the purpose of introduc- 

 ing some recent and very useful microscopic improvements. Among 

 the features which deserve especial mention are the full descriptions of 

 the several microscopes, the mechanical stage, the Congress microtome, 

 and the large assortment of objectives. Those interested in the very 

 latest improvements in microscopic apparatus would do well to obtain 

 a copy. 



Cynewulfs Elene. Edited by Charles W. Kent. 1 3°, 149 pp. Ginn 

 & Co., Boston. (Price, 65 cents.) 



In the introduction to this work the editor gives an account of the 

 manuscript, author, theme, plan, and literary merit of the poem. A 

 metrical introduction is also included, giving the marked characteristics 

 of Old English verse. The Bibliography, which occupies four pages, 

 is of especial interest. 



The text is accompanied by the Latin original at the foot of each page. 

 The 133 1 lines of the poem are numbered for easy reference. The 

 notes are full, and frequent reference is made to Cook's Sievers' Gram- 

 mar, and manv of them are transcriptions from the author's Teuto)iic 

 Antiquities in Andreas and Elene. A complete glossary closes the 

 volume. 



Animal Physiology. By Wesley Mills, M.D. 8°, 700 pp. 505 

 figures. D. Appleton & Co., New York. 



This text-book of Physiology by Prof. Mills, of McGill LTniversity, is 

 a very dift'erent book from those which we have been accustomed to. 

 The same advance which we have noticed in other branches of science 

 is evident here. As a basis for the study of medicine or of the outlines 

 of biological science, no better book can be found at the present 

 time. The first hundred pages relate more especiallv to biology. The 

 whole subject is presented in concise, but very intelligible language, 

 which with the abundant illustrations admirably adapts the book for 

 college instruction. Each chapter is closed with a summary of its 

 contents. 



Embryology has been marshalled to illustrate physiology in a skilful 

 manner. While comparisons are frequently made between the organs 

 of man and other animals, the author especially guards against the 

 gratuitous assumption that the action of similar organs is the same 

 in man and the lower animals. The demonstration of a function in a 

 quadruped is only to be used presumptively in reasoning on snnilar 

 functions in man.
