inflammation is altendecl by increased action of the heart and 

 at.eries. The abo'o^e class of diseases is, on the contrary, accom- 

 panied by a want of tone (atony) in these orijans, as well as by an 

 irritability of the nervous S3'stem. None of them require lowering 

 measures, but, tonics and generous living are demanded, I have 

 included worms in the classification, because these parasites pro- 

 duce a lowering effect, and rarely infest to any extent a strong 

 healthy subject, prefemng the delicate and half starved puppy, to 

 the full-grown and hardy dog. 



^ CHOREA. 



Chorea, or St. Vitus's dance, may be known by the spasmodic 

 twitches which accompany it, and cease during sleep. In slight 

 cases the spasm is a mere drop of the head and shoulder, or some- 

 times of the hind quarter only, the nods in the former case, or the 

 backward drop in the latter, giving a very silly and weak expres- 

 si(m to the animal. Chorea is generally a consequence of dis- 

 temper, so that it is unnecessary to describe its early stages. It 

 rarely destroys life, though it is occasion lly accompanied by fits, 

 and the sufferer ultimately dies, apparently from exhaustion. Of 

 the exact nature of the disease we know nothing, the most careful 

 examination of the brain and spinal cord leading to no decided re- 

 sult. In the treatment it is desirable to ascertain the existence of 

 worms, and if they are found, no remedy will be likely to be bene- 

 ficial, so long as they are allowed to continue their attacks. If
