 cardiac end,—and, together with the small intestines, was lined with white powder and contained more of it enveloped in much red mucus. This powder proved to be arsenic. About the middle of the small intestines a small ulcerated opening was found, through which some arsenic had escaped.

The following cases which have come under my own notice during the last five years are also worthy of observation. In a case submitted to me on the part of the crown in 1841, which has been adverted to above for another purpose [p. 265], the body after being three months interred was found with the head and face decayed and putrid; but the muscular substance was little changed; and the inspectors were particularly struck with the state of preservation of the body, and also with the very distinct state of inflammation seen over almost the whole external and internal surfaces of the alimentary canal,"—a description, the accuracy of which I had afterwards an opportunity of verifying. In the case of Mr. Gilmour (p. 265), whose body had been buried 101 days, the external parts were more decayed; but the alimentary canal appeared equally entire both to the original inspectors, Drs. M'Kinlay and Wylie, and likewise to myself three weeks later. But the following instance, in which I was consulted in 1839, is the most remarkable one of the kind that has hitherto occurred to me; because the observations then made were the result of an express experiment in a medico-legal investigation. The history of this case, which arose from small doses of arsenic frequently administered, has been already given above in some detail [p. 250]. Arsenic not having been detected in the contents or tissues of the stomach, and the trial of the individual suspected of giving the poison being necessarily postponed for some months, I recommended that a third examination of the body,—for it had been twice disinterred for inspection within ten days after death,—should be made at as distant an interval as possible, in order to ascertain whether it underwent preservation from decay. It was accordingly disinterred again, five months after death. It had an ammoniacal, but not a putrid odour. The skin was here and there covered with a thin sebaceous matter, at one or two places stripped of the epidermis, but for the most part natural in appearance, firm, and elastic. The nails were loose. The muscles of the head and near the tops of the scapulæ were adipocirous, on the chest and abdomen obscurely fibrous in texture and hardened, but elsewhere unaltered, and "in the lower extremities so perfect that they might have been used for an anatomical demonstration." The liver and lungs were also in a state of good preservation, and the latter crepitated when cut. The other viscera had been removed at the previous examinations.

It may be added that the experiments of Klanck on dogs adverted to above have been more recently repeated by Hünefeld on rabbits and mice, with precisely the same results. The animals were sometimes left in the air, at other times buried, and generally in a moist place. In every instance putrefaction made more or less progress
