sidered a of this paper. It may be worth while to narrate briefly the history of the case. A parcel consisting of a wooden case reached Howrah from Patna iu August 1891, addressed to some person in Calcutta. It remained unclaimed for sometime. Having noticed a dark-coloured offensive liquid issuing from the box, the Railway authorities had the parcel opened, and the corpse of a young Mahomedau womau was found in it. The body in due course was sent to the Civil Surgeon, Howrah, for autopsy and report. The Civil Surgeon forwarded the stomach with a portion of liver, the heart and portions of large intestines separately in three glass bottles for analysis. He suspected it was a case of arsenical poisoning, and drew the attention of the Chemical Examiner to " a peculiar bright yellow deposit on the endocardial lining of the left ventricle." The stomach as received in this Department, was found cut open, and although it had been lying immersed in spirit for some time, patches of congestion could still be discerned; the congested spots, as well as other parts of the mucous membrane, were covered over with a layer of mucous mixed with fiue dirty white particles.

The most important post mortem appearance, however, which forms the subject of this paper, was the peculiar staining of portions of the endocardium lining the ventricles of the heart. The heart as received in the Chemical Examiner's Department was found cut open and There was nothing partiits cavities exposed. cular to note in the general appearance of the

In the left ventricle the yellow patch extended from the apex of the heart upwards running parallel and close to the posterior border of the septum veutriculum to about half inch below the insertion of the mitral valve, and then curving downwards to a point about half inch above the apex. The long arm of the arch measured about 1*9 inches and the short arm about 1-25 inches; it was nearly of an uniform breadth throughout, measuring between three-fourth to half inch except the free end of the short arm which was found tapering. In the right ventricle the yellow patch was of an irregular square shape touching the apex of the heart with one of its sides, each side of the square measuring about 1*125 inches. The endocardium lining the smaller musculi papillares and column? carneae was affected, the muscle substauce being free from infiltration with any yellow particles. The endocardium lining the larger musculi papillares as well as other parts of the ventricles, the auricles, the valves and the vessels entering into and issuing from the heart was free from yellow

deposit.

In the post mortem report the yellow stain mentioned to have been detected in the left ventricle only, and the heart was described as soft from decomposition and containing no ante or post mortem clots. Whether the yellow stain in the right ventricle developed subsequent to the post mortem examination, or that it escaped the notice of the officer who conducted the autopsy, cannot be definitely ascertained. was

sometimes discovered on the mucous coat of the stomach and the intestines as were noticed in this case too in the large intestines; these are usually referred to the formation of tri-sulphide of arsenic. But such deposits, as far as I am aware, have not hitherto been observed in the heart. It is reasonable to suppose that the yellow deposit in the heart was due to the action of are

sulphurretted hydrogen generated during put-

refaction on the arsenic deposited in the tissues ; but it is difficult to account for the irregular distribution of the sulphide. It is possible that arsenic may not be uniformly distributed throughout the structure of the heart, but that certain portions possess greater power for retaining arsenic than others. It is well known that in cases of arsenical poisoning, the element is not uniformly distributed throughout the structure of the liver.
