portions of the systematic account of the fishes are admirably illus- 
trated and the accompanying charts of geographical distribution of 
families, etc., add much to the lucidity of the presentation. This 
volume is undoubtedly bound to rank high among its predecessors in 
this excellent series.

Essays on Transformism. — Professor A. Giard! has collected 
and published in book form seven of his essays which appeared dur- 
ing the last twenty-five years and which all deal with evolutionary 
matters. The essays, which are in no essential respects changed 
from their original form, deal with the history of transformism, the 
embryology of ascidians and the origin of vertebrates, biology and 
taxonomy, the factors of evolution, Lamarck's principle and the 
heredity of somatic variations, convergence in pelagic forms, and 
animal symmetry ; and afford a convenient collection for those inter- 
ested in the evolutionary speculations of this well known French 
biologist.

Morphology and Anthropology.? — The growth of anthropology 
particularly in its relations to morphology is well exemplified in the 
last number of the Cambridge Biological Series by Duckworth. ‘The 
object of the volume is to set before the student a concise exposition 
of man's place in Nature as determined by natural history methods. 
The first part of the book deals with this question from the stand- 
point of comparative anatomy and describes in an abbreviated way 
the systems of organs in the mammals and especially in the primates, 
devoting particular attention to the crania and teeth. Then follows 
a condensed account of human embryology, after which anatomical 
variations are taken up. These fill the greater part of the volume, 
the last section of which deals with paleontological materials of 
importance to anthropology. The condensation of so much sub- 
stance into so small a space often seriously interferes with an ade- 
quate treatment of the subject and one is often led to suspect that 
the volame may be found more acceptable to the student who 
is cramming for an examination than to the one who is seriously 
engaged in a real study of anthropology; nor does the preface sug-
