358 PROCEEDINGS: BOSTON SOCIETY NATURAL HISTORY. 
The botany of the Lowell Free Courses was conducted by Mr. 
B. H. V an Vleck and in continuation of that taken up last year; 
namely, the study of a limited number of representative forms with 
special reference to the more important structural and physiological 
questions. Fifteen lessons of two hours each were given. The 
work this year was confined almost entirely to the Fungi. An 
abundance of material had been provided, chiefly for use with the 
microscope. About 30 persons have been members of the class, 
and of these, 20 were quite regular in their attendance. Ten of 
these presented themselves for examination and all passed. 
The first year of a five years’ course on elementary zoology, con¬ 
sisting of seventeen lessons of two hours each, was given by the 
Curator, beginning Oct. 20, 1900, and ending March 17, 1901. 
There were fifty tickets issued and the average attendance was 
twenty-five, but out of this number only nine presented themselves 
for examination. This was due to the fact that a considerable 
number of those in constant attendance were old pupils who had 
already been through the last five years’ course and had graduated. 
Seventeen lessons of mixed lecture and laboratory work of two 
hours each were given, illustrated as usual by specimens and 
diagrams.
