XXXVII. Concerning Aneuryfms in the ^bigh. By Benja- 
min Gooch, Surgeon at Norwich. 
Redde, May 19, the calc defcribcd in the preceding pa- 
per, we obferved a divilion of the femo- 
ral artery into two trunks of equal lize, running parallel, 
and fo near together, as that we could conveniently in- 
clude them in one ligature with the needle, avoiding the 
nerve, after railing them up with the difledling forceps, 
by a fmall portion of the connedting cellular membrane. 
And here we found no occalion to take up any other vei- 
fel. This makes the third inllance in amputations of 
the thigh, in which I have obferved fuch a lujus natura 
in the arterial fyllem; hence I am inclined to think it not 
improbable that this has often happened, though I do 
not find it has been noticed by any other furgeon. The 
remark may prove of fome pradtical ufe, as I have hinted 
in my Treatife on Wounds, p. 78. in refped: to aneu- 
ryfms in the thighs. It might indeed reafonably be 
feared, where there is only one trunk of the femoral ar- 
tery without a divilion, which is commonly fuppofed 
to be the general cafe, that the lateral and communi- 
cating branches would not fufficiently enlarge, to carry 
on the circulation of the blood, and preferve the life and 
ufe of the limb after the operation for an aneuryfm.
