There is the same vesicular inflammation of the tongue in the dog which has been described (page 67) as found in the horse. The dog will not eat, he will not or cannot open his mouth, and he resists the attempt to open it with all the strength he has; a great quantity of saliva is running from his mouth; and he has a peculiarly anxious look. It has been mistaken for locked-jaw, or the commencement of rabies.

The swelling in the horse is usually confined to the tongue. In the ox it sometimes spreads over the whole of the face and neck; and in the dog the cheeks and the whole of the mouth are involved.

On opening the mouth the cause of all this is plainly seen. A red or dark-purple bladder extends along the side of the tongue, and more under than in other animals.

The same lancing from end to end, the same Washing of the mouth with tincture of myrrh while the wounds are healthy, or with the solution of chloride of lime when they become foetid, will speedily set all right, especially if one or two doses-of physic are given.

This, perhaps, is the proper place to refer to the prevailing opinion of the advantage derived from worming dogs. They are supposed to be broken of their propensity to gnaw every thing within their reach, and to be in a manner secure from becoming mad; or, should they be tabid, it is said that they will never bite.

All this, however, is perfectly fallacious. No dog was ever broken of his trick of gnawing things by the operation of worming. He will have a sadly sore mouth for a few days, but when that gets well he will gradually become as mischievous as ever.

As to worming preventing the dog from biting when rabid, it is hard to' conceive how the removal of a little dense tendinous substance enveloped in the folds of the fraenum, or bridle of the tongue, and destined to assist the tongue in the act of lapping, can have any thing to do with rabies.

The plain fact, however, is, that Worming is no preventive either against the disease, or the disposition to bite when under its influence,
