flux of blood would admit the application of bandage; five hours 
after, a frefli flux of blood appeared, and a ftri6t bandage was 
applied : At the lame time, a boy, about 12 or 14 years of age. 
had his leg alfo cut off below the knee, to whole Hump divers 
fuccefslefs applications of this ftyptic were alio made, before it^ 
was bound up, and in lefs than an hour after, a frelh flux ot 
blood happened, and liridl bandage was added: Some hours 
after thele operations, both thele patients fuffercd intolerable 
pain; in three days, the applications were taken off, and had 
any peribn, a ftranger to what was done, leen the flumps, he 
would have fuppoied nothing lefs than an actual cautery had been 
applied, and have occafioned luch large efchars, and lo frightful 
an appearance; which lufficiently demonftrated, that this vulnerary 
powder was a violent cauftic. 
Trials of llyptics have been commonly pradlifed on the bodies 
of quadrupeds, to commend them to the publick; but it is not 
without cauie, that pretenders to fuch remedies have made choice 
of younger animals, as dogs and calves, ^c. for that purpofe ; 
but fince the only ftandard of their ufe is their fuccds on human 
bodies, we Ihould make our experim.ents on thole animals, whofe 
bulk and age bear a proportion to them; for nothing is more 
obvious in wounding the arteries of living animals, than that the 
protrufion of their blood bears a proportion to their bulk; and in 
diffedion, the arteries of a Fcetus are remarkably thinner than 
thofe of an adult, and thofe of aged perfons grow ft ill thicker, 
and frequently become cartilaginous, and at length entirely 
bony.
