 vious cold having weakened the legs, the warmth is 

 only a temptation, or a drav;ing of the blood and 

 juices to that part ; and the limbs hence fwell, and 

 greafe follows. Does a horfe work violently, and 

 yet gets but little food, he falls into a fiate of debi- 

 lity ; that is, he becomes thin and weak. Now his 

 weaknefs is general and univerfal ; but thofe parts 

 the fartheft from the fource of life, from the fpring 

 of the whole, and the fountain of animal warmth, — 

 which fource, fpring, and fountain, is the heart ; — ' 

 the parts, as I have faid, that are the fartheft re- 

 moved from this, which are the hind legs, will, it is 

 evident, fuffer the mofl ; and hence the blood accu- 

 mulates in them, the parts not having ftrength to pro- 

 pel their contents ; and from this accumulation 

 cracks take place, and greafe follows. Standing in 

 wet litter may bring it on; and the obliquity of the 

 ftall, likewife, by weakening the parts. 



Greafe, it may be gained from this, may be the efted 

 of too full condition, or it may be occafioned by too 

 little; that is, by weaknefs. It therefore becomes 

 efientially neceflary, whenever a cafe of greafe oc- 

 curs, to confider whether it is brought on by the 

 exertion being greater than the fupport, or the fup- 

 port greater than the exertion ; for, in the one cafe, 

 we muft feed the horfe liberally, and leffen his work ; 

 but, in the other, we muft diminifli his food, and in- 

 creafe his exercife.
