I 76 ] 



Thefe are the fads which the academy or- 

 dered us to confider and verify. In order to 

 try the experiment we caufed M. la Fofle to cut 

 off 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 ilump with a cap of a pig's bladder 

 to keep it on •, he took off this dreffnig in a 

 quarter of an hour, and three of the arteries 

 weie ftaunched, 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 

 silfo topped in this vcild in fix minutes. 



He cut off the kg 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 

 purpofe : however he applied the powder fecur- 

 ed 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 v/as 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 bafe of which adhered ffrongly all 

 round to the internal coat of the artery, its 

 other extremity turned inward into the veffel ; 

 wiien this conic body was macerated in v/ater,
