 bat that there are yet caufes of farcy, which will 

 never produce glanders : thefe, not improbably, 

 may hold fome analogy with fuch as are com- 

 monly called fcorbutic affe6lions, in the human 

 animal. It is a pity, that nature (hould abfo- 

 lutely compel us, in fpite of hypothetical inge- 

 nuity, to hold glanders and farcy as diftin6l ma- 

 ladies, by permitting us to cure the latter only, 

 whilft the former remains an everlafling oppro- 

 brium of the veterinary art. 



PLICA POLONICA, 



Is a contagious difeafe, affecting the human 

 and other animals, particularly horfes, wolves, 

 and dogs, in a certain diftrift of Poland, in 

 which the hair is faid to become alive and 

 bleed. It is chiefly confined to infancy and 

 youth. Previous lymptoms, fpafms, pains in 

 various parts, flow fever, and difeafed eyes ; all 

 which ceafe on the irruption of the Plica. The 

 hair grows rapidly, and there is a copious fe- 

 cretion of mucus at the roots, by which it is 

 inextricably matted together. A fetid fmell is 

 emitted, with fwarms of vermin. The Poles 

 never attempt any remedy, fuppofing the dif- 

 eafe to be a falutary efPort of nature, to diflDur- 

 then the body of a load of peccant and danger- 

 ous humours. — Manchefler Meinoirs, I fliould
