 tor, who not knowing the circulation of the 

 blood, made a ligature upon the lower part, 

 inftead of the upper-part of the vein from 

 whence the blood flowed ; and whilft he tried to 

 (top it in the part from which it did not flow, 

 the horfe died. 



I faw the fame fault committed upon horfes 

 in whom the faphena was divided ; among 

 others upon one who died while they were 

 Hopping the vein, becaufe they made the liga- 

 ture above, inftead of making it below. Such 

 as are more timorous than ordinary ufually make 

 two ligatures and divide them in the middle ; 

 but there muft never be but one upon what- 

 foever vein.

They Hop up veins for different caufes, un- 

 der a notion that they are the vehicles for cer-

 in horfes, who became blind ; and that muft 

 be very prejudicial to every other part, becaufe 

 thereby they flop the courfe of the fluids. But 

 there is yet fomething more, which is, that I 

 am perfuaded that this operation, independent 

 of the accidents it occafions, is ever ufelefs, for 

 it is falfe that the veins carry any nourifhment to 

 the parts, for they ought to know that the ar- 

 teries do that office.
