tary system; 2, skeletal and muscular systems; 3, nervous system and 

 psychopathic traits; 4, mental traits and movements; 5, sense organs; 6, 

 nutritive system; 7, respiratory system; 8, execretory and reproductive 

 systems. As these cards accumulate they furnish information concern- 

 ing the location of data needed for studying the nature of the inheri- 

 tance of specific traits, for tracing their descent and recombination in 

 given pedigrees, and for demographic and statistical studies. 



3. To train field workers to gather data of eugenical import. Coop- 

 erating with the Biological Laboratory of the Brooklyn Institute of 

 Arts and Sciences, of which laboratory the Director of the Eugenics 

 Record Office is also director, there has been given for six weeks, 

 during July and August in each year, beginning in 1910, at the Eugenics 

 Record Office, a training course for field workers in eugenics. This 

 work has been under the direct supervision of the Director, assisted 

 by Dr. Harry H. Laughlin, superintendent of the Eugenics Record 

 Office. Enrollment in this course has been as follows: 14 in 1910, 25 

 in 1911, 21 in 1912, 28 in 1913, 20 in 1914, 13 in 1915, 20 in 1916, 

 13 in 1917; total 171. 



The course of instruction comprises 25 lectures on human heredity 

 and eugenics, with special reference to conduct; also daily laboratory 

 work on the following topics: Charting family pedigrees; constructing 

 and using mechanical, chemical, and statistical models for illustrating 

 the principles of heredity; tracing the descent and recombination of 

 human traits in actual pedigrees; analyzing such pedigrees in the 

 light of the existing knowledge of heredity; analyzing statistics given 

 in institutional and federal reports; statistical studies on variation in 

 plants and animals; studies in the elements of biometry; physical and 

 mental measurements in man, with special reference to the Binet 

 and Yerkes-Bridges tests. Clinical studies are made at institutions 

 for various types of the socially inadequate. Field trips are made for 

 the purpose of securing family pedigree records at first hand. 



The Eugenics Record Office keeps in close touch with all graduates 

 of this course, most of whom subsequently are actively engaged pro- 

 fessionally in eugenical work, many of them becoming field investi- 

 gators for this office and for State institutions. 



4. To maintain a field force actually engaged in gathering eugenical 

 data. The special field studies which have been carried on by the 

 Eugenics Record Office independently have included ilivestigations of 

 the "Ishmael" tribe of Indiana, the Amish sect of Pennsylvania, 

 albino families of Massachusetts, the "Nam" family of New York, 

 the "Jukes" of New York, skin-color studies in New Orleans and in 

 the islands of Bermuda and Jamaica, Huntington's chorea in New 

 York and Connecticut, pellagra in South Carolina, consanguinity in 

 Outer Long Island, Maine, the "Hill Folk" in Connecticut, community 

 studies in Woodbury (Connecticut) , steriHzed men in the Jeffersonville
