For feveral years agone a certaiaperfon did with great 
amazement tell me, that when he was pafling a cer-

to fee the manifold fmall arteries,, that can^^ forth from 
the great one^ and which wore fpre^ into feveral 
branches, and turning came into one again, and were 
re-united, that at laft they did pQjwerrout the blood a-
