Inflammation of the edges of the glottis, and particularly of the membrane which covers its margin, is often seen, and accounts for the harsh guttural breathing which frequently accompanies dumb madness. The inflammatory blush of the larynx, though often existing in a very slight degree, deserves considerable attention. The appearances in the trachea are very uncertain. There is occasionally the greatest intensity of inflammation through the whole of it; at other times there is not the slightest appearance of it. There is the same uncertainty with regard to the bronchial tubes and the lungs; but there is no characteristic symptom or lesion in the lungs. Great stress has been laid on the appearance of the heart; but, generally speaking, in nine cases out of ten, the heart of the rabid dog will exhibit no other symptoms of disease than an increased yet variable deepness of colour in the lining membrane of the ventricles. No dependence can be placed on any of the appearances of the oesophagus; and, when they are at the worst, the inflammation occupies only a portion of that tube. With regard to the interior of the stomach, if the dog has been dead only a few hours the true inflammatory blush will remain. If four-and-twenty hours have elapsed, the bright red colour will have changed to a darker red, or a violet or a brownish hue. In a few hours after this, a process of corrosion will generally commence, and the mucous membrane will be softened and rendered thinner, and, to a certain extent, eaten through. The examiner, however, must not attribute that to disease which is the natural process of the cession of life. Much attention should be paid to the appearance of the stomach and its contents. If it contains a strange mingled mass of hair, and hay, and straw, and horse-dung, and earth, or portions of the bed on which the dog had lain, we should seldom err if we affirmed that he died rabid; for it is only under the influence of the depraved appetite of rabies that such substances are devoured. It is not the presence of every kind of extraneous substance that will be satisfactory: pieces of coal, or wood, or even the filthiest matter, will not justify us in pronouncing the animal to be rabid; it is that peculiarly mingled mass of straw, and hair, and filth of various kinds, that must indicate the existence of rabies. When there are no solid indigesta, but a fluid composed principally of vitiated bile or extravasated blood, there will be a strong indication of the presence of rabies. When, also, there are in the duodenum and jejunum small portions of indigesta, the detection of the least quantity will be decisive. The remainder has been ejected by vomit; and inquiry should be made of the nature of the matter that has been discharged.
