THE OUTLINES of a university extension course of six lectures on 
the physiology of plants, which is being given at Tomah and Apple- 
ton, Wis., by Dr. Charles R. Barnes, have been distributed. The topics 
of the lectures are as follows: ‘How plants forage; How plants eat; 
How plants breathe; How plants grow; How plants move; How 
plants multiply.” 
Proressor J. E. Humpnrey has given in the American Naturalist 
(Dec.), under the title “The comparative morphology of the fungi,” 
a very useful outline view of the conclusions contained in the last four 
arts of Brefeld’s “ Untersuchungen aus dem Gesammtgebiete der 
<ologie;” views with which not merely every mycologist should be 
familiar, but every student of botany. 
A LEARNED, interesting and suggestive lecture by Mr. Charles F. Cox 
of New York city, on the stion, “ What is a diatom ?” is given In 
agement of the study of pure science, based upon the history of the 
development of knowledge as influenced by the study of these organ- 
isms.
