 The question as to the possibility of acute gastritis being produced by natural causes is one of very great interest to the medical jurist. For its possible occurrence is the only obstacle in the way of a decision in favour of poisoning, from symptoms and morbid appearances only, in certain cases by no means uncommon, which are characterised by signs of violent irritation during life, early death, and unequivocal marks of great irritation in the dead body, namely, bright redness, ulcers, and black, granular, warty extravasation. In regard to these effects, it may with perfect safety be said, that they can very rarely indeed all arise from natural causes; and for my own part, the more the subject is investigated, the more am I led to doubt whether they ever arise in this country from any other cause than poison. The possible occurrence of a case of the kind from natural causes must be granted. But this concession ought not to take away from the importance of the contrary fact as one of the particulars of a chain of circumstantial proof.

In whatever way the fact as to the existence of idiopathic acute gastritis may eventually be proved to stand, an important criterion of this disease, as of cholera, will be that the sense of burning in the throat, if present at all, does not precede the vomiting.

9. Inflammation of the Intestines in its acute form is more common than inflammation of the stomach, as a natural disease. It is generally accompanied, however, with constipation of the bowels. Acute enteritis, unless we choose with some pathologists to consider cholera as of that nature, is very rarely attended with purging.

There is a variety of intestinal inflammation, observed only of late by pathologists, but now well known, which bears a close resemblance to the effects of the irritants. It is a particular variety of ulceration commonly situated near the end of the small intestines, accompanied at first with trifling or insidious symptoms, and terminating suddenly in perforation of the gut. It begins with tubercular deposition under the mucous membrane in roundish patches. Then an ulcer appears on the middle of one or more of these patches, gradually spreads over them, and at the same time penetrates the other coats. At last when the peritoneal coat alone is left, some trifling accident ruptures it, the fæcal matters escape into the sac of the peritonæum, and the patient dies in great agony in the course of one or two days, or in a few hours. Such cases, if not distinguished by the symptoms, will be at once recognized by the morbid appearances. Perforation of the intestines, with similar symptoms, also takes place without the previous tubercular deposit, by simple ulceration of the coats.

Another form of intestinal inflammation may also be here particularized, because it imitates the effects of the irritants in the cases in which they prove slowly fatal. It is a form of aphthous ulceration
