a doubt that this is due to the solvent action of the gastric juice. If substances in a state of solution fit for absorption can find their way into the system more rapidly through the rectum than through the stomach, yet the solvent power of the fluids of the rectum upon solid substances cannot, of course, be compared to that of the gastric juice. I have delayed the publication of these experiments in the hope of being able to add to them some observations on the human subject. But there are here so many difficulties in the way of obtaining unequivocal evidence, that I have now put forward these experiments, not as the most striking, but as fair representative ones of those I have performed upon animals, in order that if any should deem them worthy of attention, the observation of others may be directed to what seems to me to

ATTEMPT TO RESTORE TO ITS NATURAL APPEARANCE A PUTREFIED DEAD BODY, IN ORDER TO PROVE ITS IDENTITY. BY BENJAMIN WARD

RICHARDSON, M.A., M.D.,

SENIOR PHYSICIAN TO THE ROYAL INFIRMARY FOR DISEASES OF THE CHEST.

ON Saturday the 9th instant, 1 conducted an inquiry to ascertain if a human body that had undergone putrefactive change to such a degree that it was unrecognizable could be so far restored to the appearance of life as to be sworn upon in respect to its identity. As the inquiry in question, from the circumstances by which it was surrounded, has created great public interest, as it opens

either its colour or feature : it was as black as the face of the darkest negro, and had it not been white when he was taken out of the water I should say that the man would have been returned as a negro. The lips were enormously distended, and the nose was scarcely visible; the cheeks and eyelids were also greatly distended. In fact, the putrefactive changes were so advanced that it required some little determination to proceed. following, nevertheless, the course I had marked out, we immersed the body in water, and then added to the water twenty pounds of common salt; we also added gradually, in the course of the operation, one pint of common hydrochloric acid; and the body was allowed to remain under this solution for two hours. The object of this part of the process was to reduce the swelling of the features by exosmosis. The shell, being watertight, answered as a bath. Meanwhile we charged a pail of water with fresh chlorine, and then, lifting the face out of the water in the shell, treated it with the chlorine water. I also directed a stream of chlorine gas for some time upon the face. The object of this part of the process was to restore the white colour. A little before one o’clock both of the intentions we had in view were realized to a considerable degree. The tumefaction was relieved; and the face, from the deepest black, had become of the cast of light clay, common wood-ash, or the darker sort of straw-paper. When the chlorine in vapour was passing over the face the skin approached to white, but so soon as it was withdrawn the change to clay-like hue returned. So much was now accomplished that we were able to form a fair estimate of the man. We found that he was evidently a young man, not more probably than twenty-one years of age ; he had a short feeble moustache; his lower lip had a short soft beard that had not been shaven, and his whiskers corresponded; his face was naturally round and full, and indeed his body gene-

rally was well nonrished. At one o’clock we left, and returned at two. We had arranged that a stream of chlorine should continue to play over the face in our absence, but, as we had no one to leave in charge, the gas had become exhausted, and the face was a little darker when

we

returned.
