This work is a revised and enlarged edition of the book 
brought out by Professors Coulter and Chamberlain in 1got. 
Each of the seven great groups is here presented in detail, and a 
final chapter discusses the problem of phylogeny and points out 
the evolutionary tendencies. The extinct groups, notably the 
primitive “‘seed-ferns,” are now included for the first time; and 
vascular anatomy is fully recognized as a morphological subject 
of first importance. The entire presentation is thoroughly an 
systematically organized and arranged with a view to the greatest 
possible clearness. The illustrations are numerous and in large 
part original. 
Nature. The book is an invaluable record, admirably illustrated, of our 
present knowledge of the older type of seed-plants. 
A Laboratory Guide in Bacteriology. By Paul G. Heinemann, 
Associate in Bacteriology in the University of Chicago. 
Second edition, enlarged and revised. 216 pages, 12mo, cloth; postpaid $1.59 
The new edition of the Laboratory Guide is designed to cover 
the outlines for work in elementary courses in the various 
branches of bacteriology. It is intended to serve as a guide not 
only to the instructor, but especially to those practically engaged 
in applying the fundamental principles of the science. In tech- 
nique and method it has been carefully revised and brought 
down to date, and itself represents the progress made in the 
science since the first edition appeared in 1905. The Guide is 
confidently offered in the belief that it will commend itself, even 
more than did the first edition, to elementary students in 
bacteriology. 
American Journal of Clinical Medicine. This little book is peculiarly 
adapted to the needs of medical students because it takes nothing for 
, commences at the beginning of the subject, and as it advances 
from point to point in the inductive study of micro-organisms, enters 
ae the details so essential for a thorough grasp of this important 
ranch.
