The former is almost always a sequel of distemper, and may be known by the peculiar nodding of the head, or twitch of the fore-leg, which all dog owners must have seen. Shaking palsy is a general agitation of the body, without the twitching so characteristic of chorea. Chorea generally occurs as a sequel of distemper (see page 19) ; but sometimes it appears without that combination. Little can be done in either case; but nitrate of silver, in doses of 1/6th of a grain, has sometimes effected a cure of chorea. When the disease first comes on, a general tonic treatment should be tried, the first principle being to improve the general health by good food and fresh air, aided by stomachic medicines; and secondly, to give such strengthening and tonic medicines as are likely to improve the tone of the nervous system. Fresh country air is of the utmost consequence, and this alone will often dispel the attacks of chorea; but when united to a liberal diet it is doubly.likely to be successful. The puppy should have plenty of good milk, or, if that cannot be obtained, beef tea or mutton broth, with oatmeal or wheaten flour added in proportion to the looseness of the bowels.

If these are confined, they must be acted on by castor oil or rhubarb and aloes, or some of the aperients which merely act without producing much loss of strength. When the strength is somewhat improved by diet and stomachics, sulphate of zinc, in doses varying from 2 to 4 grains three times a day, may be given; or a grain or two of quinine, with 2 or 3 grains of extract of hemlock in a pill, will be likely to be serviceable, but either must be used regularly for some weeks in order to have a fair chance of success. By these means many bad oases may be relieved, or perhaps nearly cured; but with sporting dogs, if the attack is really severe, it is seldom that sufficient improvement is effected to make the dog as efficient as before. Hence, in this instance it is perhaps better to destroy him, than to persist in patching him up in a way which will only render him a burden and disgrace to his master. Shaking palsy, I have already remarked, is wholly incurable.
