ON THE 



EXCRETORY DUCT 



O F T H E 



FEET OF SHEEP: 



Bi' ROBERT R. LIVINGSTON, Es^ 



PRESIDENT OF THE SOCIETY. 



THE difeafes of animals and their cure, depending upon 

 an accurate knowledge of their ftrudure, I take the liberty to 

 mention an obfervation upon that of iheep, which indeed was 

 fo obvious, that I conceived that no farmer, and much lefs the 

 naturahft that treats of this ufeful animal, could be ignorant 

 of it ; 'till I found on fpeaking on the fubjed: to many 

 experienced hulbandmen, and particularly to many members 

 of this fociety at a full meeting, that only one of the members 

 had attended to the circumftance I allude to : Nor is it noticed 

 by Buffbn, or by Liile, who treat largely on the difeafes of 

 fheep. — This mud be my apology to thofe who fliall find no 

 novelty in the following remark : The legs of fheep are 

 furniflied with a du6t, which terminates in the fiifure of the 

 hoof ; from which, when the animal is in health, there is 

 fecreted a white fluid, but whenfickly, thefe duds are flopped 

 by the hardening of the fluid.
