PART II. THE EXHIBIT 



The Third International Exhibit of Eugenics, which was held in the Edu- 

 cation Hall of the American Museum of Natural History, was formally 

 opened with a reception on the evening of August 21st, 1932. The president 

 and officers of the Congress, with the Museum authorities who were the 

 hosts of the Congress, received the guests who included several hundred 

 persons most interested in the development of eugenics, both as a pure and 

 as an applied science. The guests thus included many men of science as 

 well as persons concerned with aiding research. 



In all there were 267 exhibits which covered approximately 10,000 square 

 feet of wall space, besides occupying numerous cases and tables. The ex- 

 hibit remained open until October 1st, 1932, during which time the attend- 

 ant registered over 15,000 visitors.
