 honored in 1887 with the award of the Henry Draper medal for his 

 work on astronomical physics. In 1876 he was elected a vice-presi-

 which number about 100, he prepared " Reports on the Department of

The raw material of the investigation is found below 

 in the lists of men of science and their relatives. Sta- 

 tistical treatment of these data will follow. They are 

 arranged so that any competent observer can test their 

 validity. While great effort has been made to have the 

 details reliable, it is possible that mistakes may be found 

 in the designation of relationship, but it is thought that 

 such mistakes are few if any. 



The Men of Science and their Near Relatives 

 OF Distinction 

 The names of the men of science and their near rela- 

 tives of distinction are given at the left of the page. The 

 name of the man of science comes first and is followed by 

 a short dash. The names of the relatives follow and are 

 preceded by the letter or letters which tell the relation- 

 ship. The first name, for example, is Allis, Edward 

 Phelps; he has a cousin (FSiS, a father's sister's son), 

 Callahan, Henry White, whose work is in education. The 

 biography of this relative is found in ' ' Who 's Who in 

 America." When the name of a relative is printed in 

 small capitals it shows that the person is known for wort
