great pains, especially at nights, in her knee and thigh, yet could not feel 

 when I touched those parts. Her fever was now increased again, and she was 

 delirious at times. I advised her friends to continue the use of the fomenta- 

 tion, which they did almost night and day. About a month after there was a 

 discharge of a black fetid matter, at a small orifice about the middle of the 

 inside of her thigh, which I enlarged to obtain a better discharge. I likewise 

 cut into a tumor that appeared on her knee, but found in it only wind. About 

 a month or 5 weeks afterwards, to my great surprise, I saw that nature had 

 made a perfect separation of the mortified flesh from the sound, quite round 

 the thigh, the bone of the thigh lying quite bare for more than 4 fingers 

 breadth, and without its periosteum. The flesh above was fresh and florid, 

 and had good white matter upon it. 1 now persuaded her to l^t me take off 

 her thigh, which I did about 1 fingers breadth in the sound flesh, (because the 

 flesh ran tapering down to the bone) by which I made the stump pretty even. 

 The bleeding was little, because that the veins and arteries, which were eaten 

 asunder by the mortifying matter, nature had closed again. I dressed the stump 

 with pulv. restring. mixed with album, ovor. spread upon pledgets, and dipped 

 in ol. terebinth, made hot. For the next dressings I used digestives, and per- 

 formed the rest of the cure according to the usual rules. The woman is now 

 alive. (Aug. 23, 1707.) 



%• Rcniark on the above Case by Mr. C^noper. — About the beginning of October 17<)7, I saw the 

 woman whose case is here related : she appeared to be very decrepid, and would have shown me 

 the stump of her thigh bare, but the coldness of the weather, she said, would make it uneasy to 

 her. I felt it through her clothes, and the end of the stump seemed to be not above 4 or 5 inches 

 below the trunk of her body. 



Since I have so often found the large trunks of the arteries of the thighs and legs of aged people 

 putrified, as I have mentioned in the Transactions, N® 280, and most commonly in those who have 

 had gangrenes in the legs, &c. I am apt to suspect the like happened in the crural aMery of this 

 woman j which, like a ligature, did at length put a total stop to the influent blood below that 

 stricture. 



The Manner of making Styrax Liquida, or Rosa Mailas. By Mr. James 



Petiver, F.R.S. N° 3J3, p. 44. 



Rosa mailas grows in the island Cobross, at the upper end of the Red Sea, 

 near Cadess, which is 3 days journey from Suez : it is the bark of a tree-|- 

 (taken off every year, and grows again) boiled in salt water, till it comes to a 

 consistence like bird-lime; then separated, and put into a cask, and brought to 

 Judda, and so to Mocha in June and July, where it sells from 60 to 120 dollars 



f Of the liquidambar styraciflua Linn. The styrax calamita, or common storax, is obtained from 

 a very different tree.
