The Leg being taken off at the ufual Place' (whica 
was four Inches above the Mortification ) about two 
or three Ounces of Blood iflued out from the Muf- 
cular Part ; but upon flackening the Turniket, in or- 
der to look for, and tye the Artery, not one Drop of 
Blood flow’d out ; to my no fmall Surprize. And up- 
on feeling the Extremity of the Artery, I found it 
hard and callous ; however, I fecur’d it by a Liga- 
ture, as ufual, and drefs’d the Stump. The Patient 
(who had born the Operation with the greateft Refo-

the Leg ; and having difte&ed the Artery, with its 
two confiderable Branches as far as the Tarjiit, I found 
them for the mod part oflified ; that is to fay, the 
Trunk, where it was amputated, was oflified about 
two thirds of its Circumference. About a Quarter 
of an Inch lower, the whole was bony, leaving fo 
fmall an Orifice, that it would only admit of a Hog’s 
Bridle ; not a very fine Probe, that I endeavour’d 
to introduce. A little lower, it was on one fide 
bony, on t’ other membranous ; then again an entire 
Cafe of Bone. Here and there, for the Breadth of a 
Barly-Corn, there would be no Bone at all. - I open'd 
about two Inches of the internal Branch immediately 
above the Malleoli it appearing blacker than the reft. 
After it had been wallfd, I found in it about two 
or three Drops of coagulated Blood ; and now ’tis ex- 
panded and dry’d, tis one entire Lamina of Bone, as 
thick as the Shell of a Pigeons Egg, and of an un- 
equal Surface. I difte<fted three Ramifications of this 
internal Branch into the Foot ; only one of them had 
a very fmall Bit of Bone in it, about half an Inch 
from the Trunk. The other great Branch, that runs
