Arreurlfma in the Artery \% not very much abated, tho the 
Artery has been tyed above : The Operator rn that Cafe muft 
make another Ligature on the Trunk of the Artery below

Ligatures. Hence it is, if one Ligature made above the 
wound in the Artery is not fufBcient, but the Blood ftill 
pours out from below, the Patient will fooner recover the 
Aftion and Strength of the Mufcles of the Cubit^ than 
Thofe in whom the upper Ligature proves fuflicient ^ the 
re.ifon of which is obvious to any who conGder that the 
Communicant Branches muft be larger where the lower Li-
