The Elements | of the | Science of Nutrition | by | Graham Lusk, Ph. D., Sc. 

 D., F. R. S. (Edin.) | professor of physiology at the Cornell Univer- 

 sity Medical College, | New York City | third edition, reset | Phila- 

 delphia and London | W. B. Saunders Company | 1917 | Cloth, pp. 

 1-641. 

 This third and enlarged edition of Professor Lusk's book 

 needs no recommendation to those who are acquainted with 

 his former valuable presentations of this subject. To those 

 who have not had access to Professor Lusk's book it may be 

 said that it is a thorough and scholarly presentation of the 

 general methods, data, and facts of our present day knowledge 

 of nutrition in health and disease, to which he personally has 

 contributed so much.

A Laboratory Manual and Text-Book | of | Embryology, | by | Charles 

 William Prentiss, A. M., Ph. D., late professor of microscopic anat- 

 omy, Northwestern University Medical School, Chicago | revised and 

 extensively rewritten by | Leslie Brainerd Arey, Ph. D. | associate 

 professor of anatomy, in the Northwestern University Medical School, 

 Chicago | second edition enlarged | with 388 illustrations | many in 

 color | Philadelphia and London | W. B. Saunders Company | 1917 | 

 Cloth, pp. i-viii+ 1-411. 



The second edition of Prentiss' Text-Book of Embryology 

 as revised by Professor Arey, is indeed improved and brought 

 more up to date. While preserving the general arrange- 

 ment of the book, the text has been made more readable 

 and clearer, especially to the student, by important additions 

 and some excellent new illustrations. The rearrangement of 

 some of the very long paragraphs is also of decided advantage. 

 The new chapter on the morphogenesis of the skeleton is a va- 

 luable and needed addition. It is unfortunate that this edition 

 also failed to include a bibliography, though this is to a certain 

 extent compensated by the more frequent mention of names of 

 authors and investigators. This book like its predecessor should 

 prove of great help both to teachers and students of embryology.
