I was once requested to meet a medical gentleman in consultation respecting a supposed case of rabies. There was protrusion and discoloration of the tongue, and fighting at the corners of the mouth, and intense anxiety of countenance. He had been in this state for four-and-twenty hours. This was a case in which I should possibly have been deceived had it been the first dog that I had seen with dumb madness. After having tested a little the ferocity or manageableness of the animal, I passed my hand along the outside of the jaws, and felt a bone wedged between two of the grinders. The forceps soon set all right with him. It is time to inquire more strictly into the post-mortem appearances of rabies in the dog. In dumb madness the unfailing accompaniment is, to a greater or less degree, paralysis of the muscles of the lower jaw, and the tongue is discoloured and swollen, and hanging from the mouth; more blood than usual also is deposited in the anterior and inferior portion of it. Its colour varies from a dark red to a dingy purple, or almost black. In ferocious madness it is usually torn and bruised, or it is discoloured by the dirt and filth with which it has been brought into contact, and, not unfrequently, its anterior portion is coated with some disgusting matter. The papillae, or small projections on the back of the tongue, are elongated and widened, and their mucous covering evidently reddened. The orifices of the glands of the tongue are frequently enlarged, particularly as they run their course along the froenum of the tongue. The fauces, situated at the posterior part of the mouth, generally exhibit traces of inflammation. They appear in the majority of cases of ferocious madness, and they are never deficient after dumb madness. They are usually most intense either towards the palatine arch or the larynx. Sometimes an inflammatory character is diffused through its whole extent, but occasionally it is more or less intense towards one or both of the terminations of the fauces, while the intermediate portion retains nearly its healthy hue. There is one circumstance of not unfrequent occurrence, which will at once decide the case--the presence of indigestible matter, probably small in quantity, in the back part of the mouth. This speaks volumes as to the depraved appetite of the patient, and the loss of power in the muscles of the pharynx. Little will depend on the tonsils of the throat. They occasionally enlarge to more than double their usual size; but this is more in quiet than in ferocious madness. The insatiable thirst of the rabid dog is perhaps connected with this condition of them. The epiglottis should be very carefully observed. It is more or less injected in every case of rabies. Numerous vessels increase in size and multiply round its edge, and there is considerable injection and thickening.
