cines, among ancient Phyficians, have been loft, be- 
caafe they were not underftood. Take a broken Shin 
only, which has the Skin only rubb’d off, obferve 
the Difficulty the beft and honefteft Surgeons have to 
cure it. Go to Aetius , and others, where you may 
find a fafe, eafy and fpeedy Cure ; which, as the

a Loofenefs , we may always expert the common 
good E ffects of the Ipecacuanha for a Cure. 
On the contrary, when Ipecacuanha is given againf 
an Hepatick Dyfentery , or againjl a great Dif
