to others and his constant interest and unfailing kindness in 
spending himself for others who worked under him will continue 
long to be a potent factor in the advancement of science.

MEETING OF THE BIOLOGICAL CLUB. 
Orton Hall, March 0, lOUo. 
The Club was called to order by the Vice-President, Miss 
Riddle. The minutes of the previous meeting were read and 
approved. A letter from Prof. Hine in Guatemala was read. 
Prof. Hine reported his work there as successful for the most 
part. The party was enjoying the trip ver}’ much. 
Mr. Surface was asked to take the chair. The first paper 
was by Miss Riddle on the “ Embryology of Staphylea and of 
Philotria.” The species studied were Staphylea trifoliata and 
Philotria canadensis. Before the work on Philotria was com- 
pleted R. B. Wylie, of the University of Chicago published a 
paper on the same subject. In the discussion Prof. Schaffner 
called attention to the fact that in Gray’s Manual Philotria and 
Vallisneria are placed near the Orchids while this kind of a rela- 
tionship is evidently impossible from the detailed study thus 
shown. 
Mr. York next presented a paper on Hibernacula. Mr. York 
spent his available time this summer at Sandusky studying the 
w'ater plants in the coves of the bay. Most water plants live 
over winter by means of tubers, blulis, etc., but in some there is 
a modification of the tip of the stem. These stems are much 
shortened and form bud-like structures called hibernacula. 
Mr. Morris next read a paper on “Great Climatic Changes.’’ 
He dealt only with geological changes. By means of the fossil 
remains and vegetable deposits in different strata the climate of 
the various regions in past times can be determined. Below the 
Cambrian there are no fossils but glacial evidence gives some idea 
of the climate. Several theories with regard to causes of climatic 
changes were given, prominent among which was Dr. Chamber- 
lain’s theorv of the varying amount of CO., in the atmosphere. 
In the discussion, Mr. Gleason, Mr. Hyde, Mr. Metcalf, Prof. 
Schaffner and Prof. Landacre spoke. 
The following were elected to membership: M. E. Hendriksen, 
W. C. Morse, C. A. Miner and E. P. Durrant. 
The club then adjourned. 
F. M. Surface, Sec.
