7thly. Some gentlemen could distinguish the disease by a particular look of horror and by a particular cast of the eye, which was first watery, next blood-shot, and at last yellow. 8thly, According to the diversity of the season, the pulse varied. In general, it was small and frequent, and often, when at the wrist it was not perceptible, it could be felt beating 130 or 140 at the carotids. 9thly, The tongue was universally white at the edges; and, when in March and April, some cases appeared with the fever of the typhoid form, it was black and furred in the centre. 10thly, Several of the cases, which came under Mr Grisdale’s care in February and March, had cough and dyspnœa. Mr Adrian makes a similar report at the above period, and three of Mr Whyte’s patients at Rahamania had cough and dyspnœa. 11thly, In a majority of Mr Price’s cases, he remarked an unusual dryness of the skin, and that it was with the utmost difficulty that he could ever excite perspiration. Mr Whyte says, that, “At Rahamania the skin was dry, and that he had never succeeded in exciting sweating.” These are the appearances the disease put on in the last season; and, on inquiry, I find that they were the appearances it assumed in the former season in the British army in Egypt. My friend, Dr Short, who resided some time in Persia, and who has paid much attention to the history of the plague, informed me, that, in addition to the above, he found hemorrhage a frequent symptom in the plague, which raged at Bagdad in 1800 and 1801. In one case he saw a copious hemorrhage from the eyes, which continued for nearly twelve hours. As soon as it stopped, an eruption appeared over the body very much resembling the measles. This patient, a boy of twelve years old, died on the 5th day of the disease. The duration of the disease in different persons was very different. In several instances, the effect of the pestilential contagion was the immediate extinction of life; and we had several instances of the patient surviving but a few hours the first sensation of illness. The muccadum of the dooley-bearers of the 88th regiment, about nine in the morning, exhibited the symptoms of fever. About twelve, a bubo appeared, and he died before four o’clock. In some instances, again, the patient lived till the thirteenth and seventeenth day of the disease; however, these instances were rare. Prognosis. We found that the greatest caution was requisite in giving an opinion as to the probable event of cases: in no disease was the practitioner oftener deceived. In several instances, patients who had recovered from the fever, whose buboes were doing well, and people who were convalescent, suddenly dropped down and expired. Whether this was from re-infection, or whether it was a feature of the disease; will be difficult to determine.
