CORRESPONDENCE OF RAY. 97 



the liquamen itself, which I took to be provision of bee-

 because flies may be said to have blown on the outside of 

 the bladder, and the flyblows to have eaten through the 

 bladder, it will be proper to include such a bladder in a 

 case, to defend it from flyblows outwardly as well as in-
