On the 7th, two cases of the plague, from the same regiment, were detected in the camp at Alexandria. On the 8th, the 1st and 7th Bombay regiment marched to, and encamped at, Aboukir-bay, where a pest-establishment was placed for them. On the 2d, symptoms of the plague were discovered on Dr Whyte, who the day before had inoculated himself, and he died on the 9th. On the day following, a soldier of the 61st regiment, a servant of Colonel Barlow, Commandant of Rosetta, was sent into the pest-house there, now under the charge of Mr Grisdale and Mr Rice, with the plague. On the 13th, two of six Arabs, out-servants at Rosetta, were attacked with the disease. Two men of the department marched the same road, and halted at the same stages, as the 7th regiment had done a week before. On the 22d, two men of the 10th regiment, from a permanent guard on-board a vessel under quarantine, were sent into the pest-house at Alexandria. There occurred this month 72 cases of the plague in the Indian army, viz. 2 Officers, Dr Whyte and Mr Price. 2 Cases in the 10th regiment. 1 61st ditto. 22 1st Bombay regiment. 30 7th ditto. 4 department of the com. of cattle. 1 Pioneer-corps. 10 Arab servants. -- Total 72 -- Continued fever prevailed in the army. It was the synocha of Cullen. Intermittents were still on the decline, as were likewise dysentery and hepatitis. Pneumonia and rheumatism prevailed but in a small degree. FEBRUARY. This was a very cold and wet month; yet the number of sick continued to decrease, except in the 1st and 7th regiments, in which corps the plague continued to rage. Throughout the month, the sky was cloudy; we had high winds, on 19 days it rained, and on some of these as heavily as in the monsoons in India. The thermometer moved between 55° and 63°. On the 13th, for the first time, the following cases of the plague were dismissed cured from the quarantine-hospital; viz. two Sepoys, one drum-major, and one woman, from the 7th regiment, and two Arab servants of the pest-house. At this period, too, six were dismissed from the pest into the quarantine-hospital. Till this day no native of India, who had entered the pest-house, ever returned. But so much was the dread of the distemper now lessened, that a volunteer in-steward, for the pest-house at Aboukir, came forward from the 7th regiment. On the 24th, the commissary’s clerk at Rosetta got the disease. Of five Europeans, whom we had left at Rosetta, two caught it and died. The disease here raged with the utmost violence.
