 "rhefe humours take their courfe alfo by the nof-

The three firft kinds, as I have defcribed 

 them, are not catching, except when the hu- 

 mour has acquired an acrimony by length of 

 time, which pafling by the noftrils is detained 

 in the maxillary fmufes, inflames the pituitary 

 membrane, and fwells the glands ; a fure pro-

But the fourth, which is the farcy kind of 

 glanders, being more of an eroding nature, is 

 apt to ulcerate both the lungs and pituitary 

 membrane, and is confequently infe6lious. 



It remains to mention the two other kinds, 

 the one which proceeds from a horie's being 

 over- heated ; he coughs, and firfl difcharges a 

 "limpid fluid, and after, a whitifh matter; be-

 membrane, has condenfed the lymph in the 

 fmall veflels, which caufes an inflammation, 

 •and fwells the throat, larynx and lymphatic 



gland?.
