data consisted of the records from two colleges and two secondary schools, 

 and proved to be insufficient to furnish very definite conclusions by this 

 method of treatment. The total population in the various tables that were 

 constructed ranged from 87 to 354 and the number of children from 39 to 170, 

 which in many cases were to be distributed in 6 categories. In specific 

 subjects, as languages, mathematics, and history, as well as in general scholar- 

 ship, there were indications of positive correlations between parents and 

 children, but there appeared to be no evidence of Mendelizing factors, nor 

 was there suggestion of significant variations of correlations with sex. Further 

 data are sought for. 



The work on a "eugenic" genealogy of a New England family was con- 

 tinued by Dr. Banker. 



Heredity in Cacogenic Families. 



Dr. A. H. Estabrook has completed the field work and writing up of his 

 report on the Tribe of Ishmael. The year's work involved also the study of 

 specific families, especially such as had removed into new environments 

 farther west than Indiana, the main home of the tribe. One large group of 

 this sort was found in Missouri and studied in detail. 



In addition to his main investigation, Dr. Estabrook has made short 

 studies (not cacogenic) of the Owen family of New Harmony and of the 

 Merrill family of Vermont. Since in his studies at Indianapolis he has 

 received every courtesy and assistance from the State and the head of the 

 State Board of Charities, Dr. Amos W. Butler, and has been housed in the 

 State Capitol, he has assisted the State in various ways outside of his main 

 research. Thus he has met with the Indiana Committee on Mental Defec- 

 tives at all its meetings during the year under review and advised with them. 

 He has collaborated with their field investigators to the extent of advice and 

 suggestions in their field work, and supervision of and responsibility for the 

 scientific part of the report of the committee on its work in 1921 and 1922. 

 He also gave a number of addresses and lectures before schools, churches, 

 Rotary Clubs, social clubs, the State University, the Indiana Conference of 

 Charities and Corrections, and others. Beginning December 1, 1922, Dr. 

 Estabrook is undertaking a study of the "Highlanders" of the southern 

 Appalachian Mountains. 



Heredity of Body-Build. 



During the past two years most of the Director's free time has been spent 

 on a research into the heredity of body-build in man. This research has 

 led to a study of the normal changes in body-build during development. A 

 paper on this subject was published in Eugenical News for July. To secure 

 data for the developmental curve of build, special measurements were made 

 by Misses Louise A. Nelson and Margaret Babcock on 1,000 infants of known 

 sex, age, and race at milk stations in New York City. In addition, Dr. Bret 

 Ratner, of New York City, obtained for us daily measurements of weight, 

 height, and chest-girth of 11 children at birth and each of the 10 days there- 

 after. For later life I made measurements on boys at Brooklyn Y. M. C. A.; 

 Boy's Welcome Club; New York Society for Prevention of Cruelty to Children; 

 Orphan Asylum, Brooklyn; Hebrew Orphan Asylum, Manhattan; New York 

 Catholic Protectory; Children's Village; Hebrew Sheltering Guardian Society;
