The Evolution of Sex in Plants. (The University of Chicago Science 
Series.) 
By JOHN M. COULTER, Head of the Department of Botany, The University of Chicago. 
In this work the prevalence of a sexual reproduction among plants is emphasized, the author 
showing that in many of the lower forms sexual reproduction is unknown. Sexual repro¬ 
duction is described historically as the last method of reproduction attained among plants, 
and as not replacing but as being added to earlier methods. Thus we have variation, and in 
sex reproduction extreme individuality also. The more detailed parts of the discussion are 
illustrated by cuts and drawings introduced into the text, x +140 pages, i2mo, cloth; 85 3^ net. 
Individuality in Organisms. (The University of Chicago Science 
Series .) 
By CHARLES MANNING CHILD, Associate Professor of Zoology in the University 
of Chicago. Professor Child’s work is an attempt to state, and to present evidence in support 
of, a conception of the nature of organic individuality which the author has developed as a 
result of fifteen years of investigation of the processes of reproduction and development in the 
lower animals. In these forms, organic individuality appears in relatively simple terms, and it 
is here that we must look for the key to the problem of individuality in the higher animals 
and man. 
The author has addressed himself with remarkable success to showing the wide range of 
applicability of the conception of individuality of various fields, with the result that the book 
appeals not only to the physiologist and to the botanist, but also to the neurologist, to the 
psychologist, and even to the sociologist, x +212 pages, small i2mo, cloth; 10 s net.
