ON SOUNDNESS. 23

 interferes with the action of the knee joint, and renders the 

 animal seriously crippled. 



COLD is considered as unsouuduess while the animal is 

 suffering from it as, however slight the cold may be, it is 

 difficult to ascertain if it may not be the forerunner of some 

 serious cerebral or pulmonary disease; if the cold be 

 chronic, then it is actual uusounduess, as it interferes with 

 the health of the animal, and causes him to be much weak-

ENLARGED GLANDS are considered unsoundness ; if the 

 engorgement under the jaw is of a large size, tender to the 

 touch, and if the gland at the root of the ear partakes of 

 the enlargement, and the membrane of the nose is redder 

 than it should be, we must then look on those signs as a 

 symptom of disease. 



ENLARGED HOCK is considered as unsoundness, as it is 

 generally caused from strains; and, as this joint is a compli- 

 cated one, it will be materially affected by a strain, although 

 the probability may be that the horse will stand work with- 

 out lameness; there is absolutely a weakness of the part, 

 and a possibility of lameness at any moment after a hard 

 day's work. 



There is an enlargement of the hock, caused by kicks or 

 blows, or other external injuries, which must not be mis- 

 taken for one caused from strains, as one is merely an en- 

 largement of the skin, or immediately under it, or on the 

 outside of the bone, while the other is a strain of the liga- 

 ments which confine the small bones of the hock; the one 

 caused from some external injury may be designated as a 

 blemish only. 



EYES AFFECTED are to be considered as unsoundness so 

 long as the eyes are at all affected, no matter how slightly,
