important a place to the residues of the food 

 stuffs, omitting to state that the faeces consists 

 rather of the residues of the excretions which 

 pour into the intestinal tract. 



In the article on the ' Chemistry of Respira- 

 tion,' written by M. S. Pembrey, the statement 

 is made that in Volt's respiration apparatus the 

 moisture expired by the auimal may sometimes 

 be deposited in the conducting tubes before 

 reaching the vessel where it is caught and 

 weighed. With proper manipulation, however, 

 this does not take place, and such a statement 

 should not be too lightly made when it tends 

 to invalidate a large quantity of carefully exe- 

 cuted work. 



The articles by Schafer himself are charac- 

 terized by breadth of thought and a balanced 

 judgment which often causes him to make clear 

 a middle ground between opposing theories. 

 In his article on the ' Mechanism of the Secre- 

 tion of Milk ' he is inclined to doubt that milk 

 is the product of the bodily disintigration of 

 the lactic cells, but that, as in formation of 

 saliva, granules are extruded from the cells, 

 which granules dissolve to form the milk. 



J. H. Langley has written a very complete 

 monograph on the subject of the Salivary 

 Glands, which includes his own important 

 work. 



The other authors are W. D. Halliburton, 

 Arthur Gramgee, E. Weymouth Beid, E. H. 

 Starling, J. S. Edkins, D. Noel Paton and F. 

 Gowland Hopkins, all familiar names to the 

 working physiologist. 



The edition published here is identical in 

 make up to that published in England and is 

 everything that could be desired.

 The second volume of VAnnee biologique, 

 edited by Professor Yves Delage and published 

 at Paris by Schleicher freres, follows the ex- 

 cellent lines laid down in the first volume and 

 represents the best work accomplished hitherto 

 by the various yearbooks recently established 

 in France. The subjects are treated under 

 twenty chapters, each beginning with a critical 



survey, usually written by MM. Delage and 

 Poirault, followed by a bibliography and ab- 

 stracts of most of the papers. The digests are 

 often detailed, e. g., the notice of Cope's Pri- 

 mary Factors of Organic Evolution extends to 

 14 pp., and the account of the contents of a 

 book or paper is usually clearly separated from 

 such criticism as is given. The subjects treated 

 and the number of titles given are as follows : 



The cell, 171. 



Sexual products and fertilization, 8. 



Parthenogenesis, 6. 



Asexual reproduction, 12. 



Ontogenesis, 52. 



Monstrosities, 71. 



Regeneration, 46. 



Grafting, 10. 



Sex and sexual characters, 28. 



Polymorphism, metamorphism and the alternation 



of generations, 29. 

 Latent characters, vacat. 

 Correlation, 26. 



Death, immortality, the germ plasm, 10. 

 Morphology and general physiology, 275. 

 Heredity, 57. 

 Variation, 78. 

 The origin of species, 110. 

 Geographic distribution, 50. 

 The nervous system and mental functions, 203. 

 General theories, 48. 



It is unfortunate that this recently-issued vol- 

 ume refers to 1896, instead of 1897, but the 

 preparation of these 808 large pages represents 

 a great amount of labor for which all students 

 of the biological sciences should be grateful. 



M. Binet's U Anneepsychologique (Schleicher, 

 Paris) combines the publication of special 

 papers with a review of the progress of psy- 

 chology in 1897. MM. Binet and Vaschide 

 contribute separately and in conjunction no less 

 than twenty-two ^i-esearches to the present vol- 

 ume, and there are in addition two papers by 

 M. Bourdon and one by M. Leclere. The 

 papers, which deserve special review, are 

 chiefly concerned with the individual differ- 

 ences of school children and contain many in- 

 teresting suggestions, though, as a rule, the work 

 is not carried far enough to secure definite re- 

 sults. The bibliography, compiled in the first 

 instance by Drs. Farrand and Warren for The 

 Psychological Review, contains 2,465 titles, and
