Dr. Hume, in describing the yellow fever of Jamaica, informs us, that in several dead bodies which he opened, he found the liver enlarged and turgid with bile, and of a pale yellow colour. In some he found the stomach and duodenum inflamed. In one case he discovered black spots in the stomach, of the size of a crown piece. To this account he adds, “that he had seen some subjects opened, on whose stomachs no marks of inflammation could be discovered; and yet these had excessive vomiting.”
Dr. Lind has furnished us with an account of the state of the body after death, in his short history of the yellow fever, which prevailed at Cadiz, in the year 1764. “The stomach (he says), mesentery, and intestines, were covered with gangrenous spots; there were ulcers on the orifice of the stomach, and the liver and lungs were of a putrid colour and texture[54].”
To these accounts of the morbid appearances of the body after death from the yellow fever I shall only add the account of several dissections, which was given to the public in Mr. Brown's Gazette, during the prevalence of this epidemic, by Dr. Physick and Dr. Cathrall.
“Being well assured of the great importance of dissections of morbid bodies in the investigation of the nature of diseases, we have thought it of consequence that some of those dead of the present prevailing malignant fever should be examined; and, without enlarging on our observations, it appears at present sufficient to state the following facts.
“1st. That the brain in all its parts has been found in a natural condition.
“2d. That the viscera of the thorax are perfectly sound. The blood, however, in the heart and veins is fluid, similar, in its consistence, to the blood of persons who have been hanged, or destroyed by electricity.
“3d. That the stomach, and beginning of the duodenum, are the parts that appear most diseased. In two persons who died of the disease on the 5th day, the villous membrane of the stomach, especially about its smaller end, was found highly inflamed; and this inflammation extended through the pylorus into the duodenum, some way. The inflammation here was exactly similar to that induced in the stomach by acrid poisons, as by arsenic, which we have once had an opportunity of seeing in a person destroyed by it.
“The bile in the gall-bladder was quite of its natural colour, though very viscid.
“In another person, who died on the 8th day of the disease, several spots of extravasation were discovered between the membranes, particularly about the smaller end of the stomach, the inflammation of which had considerably abated. Pus was seen in the beginning of the duodenum, and the villous membrane at this part was thickened.
