atmofpbere, at the fame time that the urinary 

 branch has its motions inverted, another kind of 

 diabetes is formed, which may be termed the aque-

 bents frequently imbibe an amazing quantity of 

 atmofpheric moifture, infomuch that there are au-

 which were previouily abforbed, into the inteftines
