Mr. Frederick Salmon, of Old Broad Street, and Mr. Wilson, of Chelsea, were kind enough to assist me in conducting the post mortem examination. On opening the chest, the heart was free from disease, with rather more water in the pericardium than natural; the lungs were completely gorged with grumous blood, and the pleura adherent on the right side. On removing the cranium, which was remarkably thin, and cutting the substance of the brain, numerous red spots presented themselves in the medullary portion; about a table-spoonful of water in each ventricle; the plexus choroides was turgid; the corpora, striata, thalami, and basis of the brain every where preternaturally injected; the cerebellum, crura cerebri, and cerebelli, in a high state of inflammation. On removing the spinous process of the vertebra, the whole cord was considerably inflamed; and opposite the two last cervical and dorsal vertebræ the cellular substance was studded with dark patches of coagulated blood, the theca vertebralis thickened, and the cord in an active state of inflammation. The larynx and pharynx bore not the slightest vestige of disease. The preparation of the cord is deposited in the museum of the London University. The post mortem examination of this case tends to prove the correctness of Professor Thompson's theory of the proximate cause and seat of this afflicting malady; and the plate accompanying a case recorded by him, in the 13th volume of the Med. Chir. Society, gives a faithful delineation of the state in which the spinal cord was found in this case. CASE OF LONG PROTRACTED CONSTIPATION. _To the Editors of the London Medical Gazette._ GENTLEMEN, Perhaps the following case may interest some of your readers, and if you think so, its insertion in your Journal will oblige Your obedient and humble servant, S. D. BROUGHTON. 12, Great Marlborough Street, Dec. 3, 1828.
