[DECEMBER 7, 1916 
Their position and their language were long a problem 
with ethnographists and linguists. Sir G. Grierson has 
in this paper satisfactorily solved the problem by a 
careful examination of their language, which he de- 
clares to be western Iranian. A full grammar and 
vocabulary of the language will appear in the appro- 
priate volume of the Linguistic Survey.—B. A. Gupta ; 
Folklore in caste proverbs.—Sarat Chandra. Mitra ; 
Some Indian ceremonies for disease transference.. In 
this paper the author has described and compared the 
different ceremonies, current in western and southern 
India, for conveying the disease-spirit, in a chariot, 
from one place to another.
