^this knov/n power .3 for having fpread feme of it on the 
naked Breaft of fome Fowls, leaving it fticking there for 
three days, I afterwards found between thedryed Varnifn 
and the Flefli the place all feftered, and fall of a yellovvilh 
Serum and Matter, but without any farther mifcbiefto the 
Eody of the Fowls themfelves. I have attempted the fagie 
thing in Dogs and Cats, but without fuccefs, for thefe 
Animals with their tongues and daws foon takeoff all the 
Varnifh from their Bodies, and fo have no hurt by it. 
Pojffibly in Horfes and like Beafts the Experiment may fac- 
ceed better, if the Varnifh has this corrofive or Gauftic 
quality upon their Bodies as it has on Poultry.
