SECTION OF BIOLOGY. 



October 14, 1901. 



Section met at 8:15 P. M., Professor C. L. Bristol presiding. 



The minutes of the last meeting of Section was read and ap- 

 proved. 



The evening was devoted to the presentation of reports on 

 summer work by members. 



Summary of Papers. 



Professor E. B. Wilson described his work carried during the 

 early part of the summer at Beaufort, N. C, where he had been 

 successful in makmg further observations upon the fertilization 

 phenomena in living sea-urchin eggs treated with various chemi- 

 cals. Professor Wilson spoke also of the meeting of the Inter- 

 national Congress of Zoologists at Berlin, which he had at- 

 tended as a representative of the Academy, and where he had 

 acted as Chairman of the Section on Experimental Biology. It 

 was before this section that papers of the greatest interest were 

 presented by Driesch, Biitschli, Roux, Ziegler, and many others. 



Professor Bashford Dean told of some of the results he had 

 obtained during his work in Japan of more than a year. Special 

 endeavors were made to obtain embryological material of the 

 important shark-types Cestracion, and ChlamydoselacJms. In 

 eggs of the former, there appeared to be a series of cleavage 

 planes in the yolk, extending out from the blastoderm proper. 

 Some CJilamydoselacJuis material was obtained. A new hag- 

 fish, intermediate in gill-characters between Bdellostovia and 

 Myxine, together with a new CJiimcBi'a, was found in deep 

 w^ater. 



Professor F. S. Lee reported briefly upon a research recently 

 made in his laboratory by Dr. William Salant upon the action 

 of alcohol on muscle. The details of this work will be com- 

 municated by the Academy later. Professor Lee then gave an 

 account of the Fifth International Physiological Congress which 

 was held at Turin in September. 



Dr. H. R. Linville described the location and work during the
