his own special views on physiology. Sometimes this personal treatment 
8 st into egotism, though much is to be forgiven to one who has 
made such extensive and profound additions to our knowledge as Dr. 
Sachs. There is hardly an important topic upon which his researches 
have not cast much light, and for a large number of principles he justly 
claims priority. : 
But this work appeals not alone to the special student of plant physt- 
ology. It can be read by any person fairly well informed as to plant 
structure and the principles of chemistry and physics, and deserves as 
wide a circle of readers in its English form as it has had in Europe its 
original German. To this the most admirable work of the translator 
commends it. We have him to thank also for the greatly extended index, 
an important part of a book, to which our German friends would do well 
to take better heed. We say nothing of the treatment of the work, tak- 
ing it for granted that most teachers are already familiar with it,and that 
all who are not will at once obtain the new edition. The imprimatur we 
the Clarendon Press is a guarantee of the excellence of the typography. 
The volume is uniform with the recently issued Goebel’s “ Outlines of 
Classification,” which is supplementary to it. With Goodale’s, Vines’ and 
Sachs’ physiologies, English students have for the present 4 pretty full 
epitome of the functions of plants.

Much of its value lies in the remarkable completeness and accu 
which references to all independent works, articles, or incidental men-

it is not supposed the list is perfect, and botanists will do their fellows, 8
