 cient for their difcovery and confequent 

 extraction j but when this does not hap- 

 pen, and the infe& is fuffeied to conti- 

 nue under the fltin, it foon fabricates 

 a thin, membranous, capfula, or bag, in 

 which it inclofes itfelf, leaving only a 

 fmall opening for its head. In this bag 

 it depofits its eggs, which are numerous, 

 and refemble nitts ; thefe daily increafe 

 in number and magnitude, and in a few 

 days the bag is diftended to the fize of a 

 large pea, by which time the nitts be*- 

 gin to hatch, and if not extracted they 

 form other bags, and at length produce 

 malignant ulcers, &c. But in Whites 

 they are feldorn fuffered to arife to this 

 maturity. After the bag is formed, it 

 ought to be extracted without breaking, 

 otherwife fome of the nitts will be left 

 in the wound, and become Chiggers. 

 When the bag, by any accident, hap- 

 pens to break, it is ufual to fill the 



wound
