Thefe are the fads which the academy or- 

 dered us to confider and verify. In order to 

 try the experiment we caufed M. la FofTe to cut 

 oft the tail of a mare as near the root as he 

 could, the blood flew out of the four arteries 

 with great force ; he applied this puff-ball pow- 

 der to the flump with a cap of a pig's bladder 

 to keep it on ; he took off this dreffing in a 

 quarter of an hour, and three of the arteries 

 were flaunched, but the fourth continued to 

 bleed very fail ; and by applying a pinch of 

 the powder to the bleeding artery, which he 

 kept to it only with his finger, the blood was 

 aJfo flopped in this veffel in fix minutes. 



He cut off the leg of another horfe about 

 ten inches above the knee ; and as the arteries 

 did not bleed, he handled them for half a quar- 

 ter of an hour in order to force them, but to no 

 piirpofe : however he applied the powder fecur- 

 cd by a pledget and proper bandage ; and there 

 was not any bleeding for three days after, al- 

 though the horfe had moved himfelf very much, 

 and was often put to pain after the operation. 

 The horfe was ordered to be killed, and hav- 

 ing opened the principal artery of the flump 

 longitudinally, we found a body of a conic fi- 

 gure about four fingers breadth above the ex- 

 tremity, the bafé of which adhered flrongly all 

 round to the internal coat of the artery, its 

 other extremity turned inward into the veffel ; 

 when this conic body was macerated in water,
