as is also true of Parts I and JII. The entire book 1s profusely and well illus- 
trated, some most helpful diagrams being included. While the book as a whole 
is too heavy for the average high-school work, it will be almost indispensable 
a reference work because of its large amount of information, its abundant 
illustrations, and its helpiul suggestions as to the significance of structures and 
their relationship to one another. A glossary of terms used and a laboratory 
guide to accompany the text are in process of preparation by the authors. It is 
unfortunate that the glossary of terms is not bound with the text including the 
terms to be explained. 
The series of texts prepared by Courter has also been increased.? In 
former textbooks hy Professor CoULTER, separate treatment was given to mor- 
phology and ecology, with work in physiology less distinctly outlined. Those 
books, while possibly not so extensively used as some others, certainly served 
as the strongest stimulus in bringing about the introduction of modern botany 
to supplant the rather mechanical and less representative work that had pre- 
vailed in high schools. The testimony of some teachers indicates that at least 
for some schools Plant Structures represents a course too difficult for the students, 
and that Plant Relations is not sufficiently representative of plant processes. 
Plant Studies is made up essentially of parts oi the two preceding books bound 
together. In the new text the author has attempted to articulate more closely

e first five eee include a presentation of ‘‘the structure, function, and 
relationship of the most obvious plant organs.” The plants selected as types in 
these chapters are all seed plants, those most familiar to high-school pupils, and 
most readily examined by inexperienced observers. Following this general dis- 
cussion, eight chapters are given to a consideration of the great groups of plants, 
beginning with Cyanophyceae and ending with angiosperms, giving an outline of 
the typical structures, functions, and habits found in each group. Chapter XIV 
treats of “Pollination,” XV of Seed dispersal,” XVI to XVIII of the leading 
families of monocotyledons and dicotyledons, XIX of ‘Plant breeding,” XX of 
“Foresty,” and XXI to XXIV of “Plant associations.” 
There are several important points in which this book is conspicuously unlike 
preceding ones by the same author. Botanical terminology is simplified in form 
and less frequently used. The types selected and the style in which they are 
presented results in a much simpler treatment of the plant kingdom than in 
Plant Structures. pxequest cir tacit of Piessowpesge concerning economic
