THE EVOLUTION OF SEX IN PLANTS. (The University of Chicago 
Science Series.) By John Merle Coulter, Head of the Department of 
Botany in the University of Chicago. 
Pp. viii -h 140. Small 12mo, cloth. 4s. net. 
In this first volume of the new "University of Chicago Science Series" Professor Coulter, the editor 
of the Botanical Oazette and the author of numerous volumes of botanical science, has given a presentation 
of the results of research showing that all reproduction is the same in its essential features and methods 
of reproduction are natmal responses to the varying conditions encomitered by plants in their life 
histories. Sex reproduction, the author says, is simply one kind of response, the sex feature not being 
essential to reproduction, but securing something in connection with the process. Various phases of 
the subject discussed include the evolution of sex organs, the alternation of generations, the differentiation 
of sexual individuals, and parthenogenesis. The last chapter, which offers a theory of sex, reviews 
the more prominent facts set forth in preceding parts of the volume, and serves both as a summary and 
a working hypothesis. 
ARTIFICIAL PARTHENOGENESIS AND FERTILIZATION. By 
Jacques Loeb, Member of the Rockefeller Institute for Medical Research. 
Pp. x-f.S12. 12mo, cloth. 10s. net. 
The first complete treatment of the subject of artificial parthenogenesis in English It gives an 
account of the various methods by which unfertilized eggs can be caused to develop by physico-chemical 
means, and the conclusions which can be drawn from them concerning the mechanism by which the 
spermatozoon induces development. Since the problem of fertilization is intimately connected with 
so many different problems of physiology and pathology, the bearing of the facts recorded and discussed 
in the book goes beyond the special problem indicated by the title.
