INDIAN VOCABULARIES CHOREA. 



LIST OF INDIAN VOCABULARIES RECEIVED FROM THE 

 WHEELER EXPEDITION. 



CIRCULAR IN REGARD TO THE DISEASE KNOWN AS 



" CHOREA." 



Smithsonian Institution, 

 Washington, D. C, January 1, 1875. 

 Dr. S. Weir Mitchell, an eminent physician and physiologist of Phil- 

 adelphia, asks the assistance of the Smithsonian Institution in obtain- 

 ing any facts in regard to the disease known as chorea, or Saint Vitus's 

 dance, and for this purpose has prepared the accompanying series of 

 questions. 



The special object of the inquiry is to ascertain whether the assertion 

 that black children are not affected with this disease is correct. 



Any data on this subject may be addressed to either the Smithsonian 

 Institution, Washington, D. C, or Dr. S, Weir Mitchell, 1332 Walnut 

 street, Philadelphia. 

 As early information as possible is desired. 

 Respectfully, 



JOSEPH HENRY, 

 Director Smithsonian Institution. 



1. To what extent do you see chorea (of childhood) among whites? 



2. Is it found more in one locality than another*? 



3. At what season do the attacks come? 



4. How often have you seen chorea in blacks of^pure breed ? If pos- 

 sible, give cases. 



5. How common is it in mulattoes? 



If you can get answers from other physicians, in addition to your own, 

 It will be desirable. 



S. WEIR MITCHELL, M. D.
