By LESTE-^ F. WARD. 



Annual address of the l- resident of the Biological 

 Society of Washington delivered Jan. 34, 1891. A 

 historical and critical review of modern scientific 

 thought relatiye to heredity, 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. Lamarcfeism, 

 Darwinism. Acquired Characters. Theories of He- 

 redity, Views of Mr. Galton, Teachings of Professor 

 Weismann, A Critique of Weismann, Neo-Darwin- 

 ism, Neo-Lamarckism, the American "School." Ap- 

 plication to the Human Race In so far as views 

 are expressed they are in the main in Hub with the 

 general current of American thought, and opposed

 of acquired characters.
