 of these glands, which does not subside for a considera- 

 ble time after the cold or fever has apparently been 

 cured. To slight enlargements of the glands under the 

 jaw much attention need not be paid ; but if they are 

 of considerable size, and especially if' they are tender, 

 and the glands at the root of the ear partake of the en- 

 largement, and the membrane of the nose is redder than 

 it should be, we should hesitate in pronouncing that 

 horse to be sound. We must consider the swelling as a 

 symptom of disease.

A horse with enlarged hock is unsound, the structure 

 of this complicated joint being so materially affected 

 that, although the horse may appear for a considerable

 son even well actjuainted with horses will not always 

 recognise the traces of former disease. After a time, 

 however, the inflammation returns, and the result is 

 inevitable. A horse that has had one attack of this 

 complaint, is long afterwards unsound, however perfect 

 the eye may seem to be, because he cairies about with 

 him a di.sease that will probably again break out, and 

 eventually destroy the sight. Whether, therefore, he 

 may he rejected or not, depends on the possibility of prov-
