can be engendered by the putrefactive fermentation of the litter. 

 HencCj the fact of the hind legs being so much more frequently 

 affected with Grease than the fore, will admit of a satisfactory expla- 

 nation, without having recourse to other reasons which might be ad- 

 vanced to account for it. 



So that the seat of the disease, has to struggle with disadvantages, 

 lo which no other part of the animal is exposed, especially after 

 inflammation has once attacked it. We are not to wonder, therefore, 

 that chops and cracks in the skin of the fetlocks, should frequently 

 appear in the winter season, even in stables which are well regulated ; 

 much less ought we to be surprised, at seeing frecjuent instances of 

 Grease in those, where there is nothing but filth and negligence. 



Now, that this disease depends chiefly upon the circumstance of 

 the affected part being exposed to great vicissitudes of heat and cold, 

 (exasperated no doubt by the other exciting causes, which have been 

 enumerated,) will, I think, satisfactorily appear, when we consider 

 how rarely we see this disease, amongst Horses which are treated 

 roughly, get a little or no dressing, and live either altogether out of 

 doors, or are housed in such open airy buildings, as merely shelter 

 them from wet, without much confining or heating the atmosphere. 

 And what may serve to illustrate this point still more clearly, is, the 

 following fact, viz. that we rarely, if ever, see this disease amongst 

 Horses so treated, even though the food which they eat, and the la- 

 bonr which they perform, are precisely of the same kind, as those 

 get, which are commonly attacked with this disease. Just as 

 it is, indeed, with the subjects of chilblain ; for hoAV rarely do we 

 see the children of the poorest peasants, who go bare-foot in frost 

 and snow, and are exposed to the utmost inclcniency of the weather
