I therefore went to a butcher's, to fee whether the gall was not 

 emptied into the maw, but 1 found that the gall bladder did not dif- 

 cliarge its contents into the maw, but farther down, where the bowel 

 grows narrower ; this gall bladder I caufed to be cut off ib as to leave 

 the vefiel through which the gall palVes, joined to the bowel, and 

 having bound both ends of thefe with a thread, I inflated the gall-

 whei-eas, on the contrary, every kind of acid, whether ufed in food, or 

 taken by itfclf, agrees perfe61Iy well with me. In fliort, we can 

 much better judge for ourfelves as to \\ hat agrees or difagrees with 

 our conftitutions, than pretend to advife other people what is good 

 diet, or the contrary. 



With regard to the curdled milk, which I have mentioned to be 

 taken out of the calf in hard pieces, it feems to me probable, tliat the 

 milk at firfi; was but lightly curdled, and that the frequent contrac-
