By LESTER F. \A^ARD. 



Annual address of the President of the Biological 

 Society of Washington, delivered Jan. 24, i891. A 

 historical and critical review of modern scientiflc 

 thought relatiTe to hei-edity, and especially to the 

 problem of the transmission of acquired characters. 

 The following are the several heads involved in the 

 discussion: Status of the Problem. Lamarckism, 

 Darwinism. Acquired Cliaracters, Theories of He 

 redity. Views of Mr. Galton, Teachings of Profes'or 

 Weis'mann. A Critique of Weismann, Neo-Darwin- 

 ism, Neo-Lamarcbism, the American "School " Ap- 

 plication to the Human Race In so far as views 

 are expressed they are in the main in line with the 

 general current of Americau thought, and opposed 

 to the estreme doctrine of the non-transmissibllity 

 of acquired characters.
