 tition along the infide of the nofe, the m.axillary 

 fmufes or cavities of the cheek-bones on each 

 fide the nofe, and the frontal finufes or cavities 

 above the orbits of the eyes -, that the vifcera, 

 as liver, lungs, &:c. of glandered horfes are in 

 general exceeding found ; and confequently that 

 the feat of this diforder is not in thoie parts, as

 is it probable it fnould ; for hov/ could fuch 

 horfes preferve their appetite, their good ap- 

 pearance, fleek and fliining coats, in a word 

 all the figns of health for many years together 

 (which many gland^ered horfes are known to 

 enjoy) with fuch diftempered bowels. 



But on nicely examining the heads of fuch 

 horfes he found the cavities abovementioned, 

 more or lefs, filled with a vifcous flimey mat- 

 ter, the membrane which lines both them and 

 the noflrils inflamed, thickened, and corroded 

 with fordid ulcers, which, in fom.e cafes, had 

 eat into the bones. Thefe finufes or cavities 

 will be better underflood by referring to the an- 

 nexed plate. 



He obferves that when glandered horfes dif- 

 charged matter from both noflrils, both fides of 

 the membranes and cavities were affedled -, but 

 when they run at one nofiril only, that fide on-

It is a curious remark of our author, that the
