By LESTER F. WARD. 



Annual address of the President of the Biological 

 Society of Washington delivered Jan. 24, 1891. A 

 historical and critical review of modern scientific 

 thought relative 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, Lamarckism, 

 Darwinism, Acquired Characters, Theories of He- 

 redity, Views of Mr. Galton, Teachings of Professor 

 Weismann, A Critique of Weismann, ^eo-Darwin- 

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

 plication to the Human Race. In so far as views

 of acquired characters.

Taking butter from milk 

 was known in the earliest 

 times. It was left for our 

 time to make a milk of cod- 

 liver oil. 



Milk, the emulsion of but- 

 ter, is an easier food than 

 butter. Scott's Emulsion of 

 cod-liver oil is an easier food 

 than cod-liver oil. It is rest 

 for digestion. It stimulates, 

 helps, restores, digestion; 

 and, at the same time, sup- 

 plies the body a kind of 

 nourishment it can get in no 

 other way.
