them into the two orifices whence the blood came. It was immediately stopped, 

 and the neck dressed up without any considerable bandage. — Walter Needham. 



June 1 ] , 1673. Another experiment was made by Dr. Needham, before the 

 R. S. A dog's crural artery was cut quite across with an incision knife, the 

 blood gushing out copiously, a lint dipped in the said liquor was applied to the 

 wound, and held upon it a little while ; when, by reason of the great glut of 

 blood, that could not be well wiped away for want of a sponge, the lint was 

 changed for a fresh one dipped in the liquor, and kept on about half an hour; 

 and being then left loose, the blood was soon staunched, the dog being then 

 unbound, licked the wound, and walked away without any ligature, and is still 

 found alive and well. 



June 18, 1673. Another trial was made before the same Society by Denys 

 himself. In the crural artery of another dog was made an oblique wide cut, and 

 the liquor in the usual manner being applied to it, the blood was staunched in 7 

 min. and the dog being then let loose, but yet kept quiet for 23 min. longer, he 

 then rose and let fall the applied compress, and went away without any bandage. 



To these experiments were added some that were made at Whitehall, before 

 the King, on two calves, by opening the crural artery, and by cutting off a leg; 

 in which the blood was completely staunched in about a quarter of an hour. 



Experiments made at Paris with the same Liquor, as described by M. Denis.

This author says, that this essence has none of the usual dangerous inconve- 

 niences ; it causes no pain at all ; being applied to the wound, it easily pene- 

 trates through the flesh, to find out and close the mouths of the arteries, with- 

 out any necessity of cutting away any thing, as you must do, if you will convey 

 other remedies thither; and the effect of it is so quick, that in about a quarter 

 of an hour, if it be well and exactly applied, the operation is performed; nor 

 need you stay several days for the falling off of the eschar to be assured of the 

 staunchness of the blood. 



The experiments he recites are these : — 



The crural artery of a dog was pricked with a lancet, presently a*button-pled- 

 get dipped in the essence was put on the wound, and kej>t on by some lint laid 

 over the pledget, and held on by the thumb. In less than half a quarter of an 

 hour the artery was so closed, that not a drop of blood issued on removing the 

 pledget. 



Two days after, the other crural artery of the same dog was laid open, and 

 having cut it quite through with scissars, a compress of lint dipped in the liquor 

 was immediately applied to it ; and half a quarter of an hour after, the compress
