 thefe humours take their courfe alio by the nof-

 and the horfe gradually périmes.

 lungs and pituitary membrane -, making more

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 patting by the noftrils is detained 

 in the maxillary finufes, 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 infectious. 



It remains to mention the two other kinds, 

 the one which proceeds from a horfe's being 

 over- heated ; he coughs, and iirft difcharges a 

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

 membrane, has condenfed the lymph in the

 and fwells the throat, larynx and lymphatic

The horfe fometimes as he coughs difcharges 

 the matter from his mouth, and when the
