MEETING OF THE BIOLOGICAL CLUB. 



Orton Hall, March 6, 1905. 



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 very 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 

 water plants in the coves of the bay. Most water plants live 

 over winter by means of tubers, blubs, 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 cliinatic 

 changes were given, prominent among which was Dr. Chamber- 

 lain's theory of the varying amount of CO.j 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.
