THE GENERAL MEETING OF THE AMER- 

 ICAN PHILOSOPHICAL SOCIETY, 

 APRIL 23-25, 1908 



The general meeting of the American 

 Philosophical Society was held at Philadel- 

 phia on April 23, 24 and 25. The opening 

 session was on April 23 at 2 :30 p.m., and 

 morning and afternoon sessions were held 

 on the following days; with an evening 

 lecture by Professor Henry F. Osbom on 

 April 24, at the hall of the Historical 

 Society of Pennsylvania, which was fol- 

 lowed by a reception to the visiting mem- 

 bers and friends of the society. The ses- 

 sions were largely attended. The meeting 

 closed with a dinner at the Bellevue-Strat- 

 ford on the evening of April 25. 



Forty-two papers were presented, cover- 

 ing a wide range of subjects. Among those 

 relating to science were the following: 



Cytomorphosis, a Study of the Law of 

 Cellular Change: Charles Sedgwick 

 MiNOT, of Harvard University. 

 Cellular change is in the direction of the 

 differentiation of the protoplasm of the cell. 

 As more and more of the undifferentiated 

 protoplasm becomes specialized, the cell 

 loses its plasticity to respond to exterior 

 influences, and the power of the cell to re- 

 produce depends upon the amount of un- 

 differentiated protoplasm remaining. A 

 blood corpuscle, for instance, which eon- 

 tains no undifferentiated protoplasm can 

 not reproduce and must die. In muscle, on 

 the other hand, the small amount of undif- 

 ferentiated protoplasm remaining in the 

 cell enables it to grow, and repair injuries.
