zontal habit. Flowering shoots of Veronica chamaedrys were made to take 
the form of an ordinary vegetative shoot by growing them as cuttings in moist 
air. Many other fascinating experiments are described. 
The book is full of suggestive theoretical discussions. In the author’s 
interpretation of these phenomena of higher plants, the responses already 
obtained in lower plants are taken into account. ‘hus, the whole manner of 
treatment is one based on the physiology of the cell itself. On the whole, the 
work is an admirable one and one which will immediately take its place 
alongside Dr, Klebs’s earlier treatise as among the first to present the subject 
of development from the standpoint of objective physiology.—BuRTON E.

“WITH THE TREES”'S is the title of a recent book which furnishes evi- 
dence of the increasing popular interest in the trees and forests. Such sub- 
jects as: When the sap stirs, The life of leaves, The work of leaves, In the 
high woods, In a hillside pasture, Trees of streets, parks, and gardens, are 
very interestingly treated by the author. The book indicates a thorough 
knowledge and familiarity with the botanical problems discussed. The usual 
tendency of popular writers to personify plants is carried to an extreme in 
many cases. While this may lend a certain vivacity to the style, the practice 
is unfortunate, because it conveys erroneous impressions of the life-processes 
and of the probable origin of structures in plants. The book is very well 
illustrated from photographs by Edmund H. Lincoln and C. B. Going.—

THE sTuDy of the life-history of truffles has lately engaged the attention 
of several French investigators. On December 10, 1900, M. Emile Boulanger 
deposited with the Paris Academy of Science a sealed paper, which was 
opened at his request on May 4, 1903. It contained a description of his 
success in germinating the ascospores of Zuber melanosporum and T. uncina- 
tum. He further described the mycelium, and a conidial stage, and announced
