the 2 large arteries, which was immediately taken up, and tied with a needle and 

 ligature. In order to discover this vessel, the agaric was removed; and though 

 the tourniquet was quite slack, the other large artery did not bleed one drop. 

 This happened about \'^ hour after the operation. After the vessel was tied, the 

 same agaric was again laid on the same part, without screwing the tourniquet, 

 and the patient became much easier; but, in about 84- hours, the other large 

 vessel burst open; and though assistance was on the spot, and it was immediately 

 tied up, she was so exhausted by the sudden loss of blood, that she died in about 

 twenty minutes. It is conjectured, that, by the 3 haemorrhages, viz. the first 

 during the operation, and the 2 after the operation, she lost between 20 and 30 

 oz. of blood. Mr. S. examined the limb after death, but found no singular ap- 

 pearance in the vessels, or the adjacent parts. 



The other woman was 24 years of age. She lost very little blood in the 

 operation, and had continued extremely well ever after. The agaric seemed in 

 this instance, to have answered the most sanguine expectations. The following 

 are the particulars of this case, as related by Mr. Warner:

Saturday, December 9, 1752, Catharine Spong, aged 24, had her leg ampu- 

 tated, about 4 inches below the knee, at 12 o'clock to-day, on account of an 

 incurable ulcer, with which she had been afflicted for 13 years. She lost very 

 little blood by the operation. Immediately after the amputation, a piece of 

 agaric, of a proper size was applied to the mouths of the principal arteries. Two 

 other pieces of agaric were applied to the mouths of 2 smaller arteries, which ap- 

 peared at some distance from the principal ones. On the pieces of agaric, dossils 

 of lint were applied, and over all a pledgit of tow spread with the common 

 digestive ; all which were kept on by the common bandages made use of in the 

 like cases, and ajjplied with the same degree of tightness as usual. 



For an hour and a quarter after the operation, the ligature and tourniquet 

 were kept on moderately tight, at a convenient distance above the knee, at the 

 end of which time it was slackened, so as to have no degree of pressure on the 

 femoral artery, as the dressings and rollers appeared very little tinged with 

 blood. The patient was much easier than Mr. W. had ever observed, after the 

 use of the needle and ligatures. Her pulse appeared very little disturbed till 

 about 4 o'clock this afternoon, when the symptomatic fever began to come on, 

 attended now and then with convulsive twitches of the stump, and thigh; for 

 which reasons, the ligature was somewhat tightened. At 7 o'clock this evening 

 the ligature and tourniquet were quite loosened ; soon after which, the convulsive
