PROBLEMS OF LIFE & REPRODUCTION. 



By MARCUS HARTOQ, M.A., D.Sc, 



Professor of Biology in the University, Cork. 



With Illustrations. Demi/ Sro. 7s. Qd. net. 



This collection of essays is primarily intended for the layman interested in biological problems ; 

 but the professional biologist will find much new or newly-arranged material also. The book not 

 onlj contains criticisms of certain schools of biological thought but embodies the author's views 

 to Mich important questions as oytoloey, reproduction, fertilisation, germination, and heredity. 

 In the essay on " Mitokinetism," a striking new conception of the forces controlling cell division 

 and of the resemblance of the cell field to an electrical held is explained. A comparative 

 criticism of the Weismannian and Lamarckian theories of heredity and their modern in- 

 terpretations will be found mosi valuable to those who have not the time to follow the 

 voluminous literature on the subject. In the chapter ou " Mechanism and Life," the vitalistic 

 tendency of the author is manifest, and the differences between living things and machines are 

 discussed in an interesting and illuminating manner. 



COMPARATIVE ANATOMY OF VERTEBRATES. 



By J. S. KINGSLEY. 



Professor of Biology in Taft's College, Massachusetts. 

 With Illustrations. Demy 8vo. li'.s. net. 



Vertebrate anatomy is everywhere taught by the laboratory method. The student studies 

 and dissects representativi classes, thus gaining an uutoptic knowledge of the various 



organs and their positions in these tonus. These facts do not constitute a science until they are 

 properlj compared 8 ed with each otbej and with the conditions in other animals. It 



i- the purposi Of the author to present a volume of moderate size which may serve as ii frame- 



hieb these taets can be grouped so that their bearings may be readily recognized 

 and a bl , brate structure may be obtained. In order that this maybe 



the basis, the various structures being traced from the un- 

 differentiated egg into the adult condition. Thi- impare the embryonic 

 the higher vertebrates with the adult Of the lower and to recognize the resemblances 



and differences between organs in the separate olasses. The illustrations have been drawn 

 sly for this wi irk.
