2dly, On any symptoms of the plague appearing, the case was instantly sent to the pest-house from the observation-room of the regimental hospital: the patient was accompanied by the medical gentlemen of his corps who attended him, and who gave the medical gentlemen at the pest-house an account of the previous treatment of the case. If any doubt remained, the patient in the first instance was placed in the observation-room of the pest-house; and, if the disease did not turn out to be plague, he was sent to the quarantine. 3dly, In every corps, and in every department, a minute inspection by the surgeon was made twice a week; and every person with the smallest appearance of ill-health was sent to the hospital. 4thly, Every corps or hospital, where a case of plague had appeared, was put into a state of quarantine; and, in such corps or hospital, an inspection by the surgeons was made at least two or three times a day; and every case with suspicious symptoms was ordered to the observation-room. 5thly, In suspected corps, it was ordered, that, under the inspection of a commissioned officer, every person should be bathed more frequently, and at stated periods; and, likewise, that all their clothing and bedding should be frequently washed and baked. To all the hospitals, ovens and smoking-rooms were attached. 6thly, Quarters of corps, hospitals, and ground of encampments, were frequently changed. 7thly, Much is to be attributed to the nitrous fumigation. In several instances it was attended with the best effects. The lamps, with this, were kept constantly burning in the observation-rooms, and in the rooms from which the cases of the plague had come. Vessels, with the materials for the fumigation, were likewise placed under the beds, and in the corners of the rooms. When our stock of nitric was at length exhausted, we substituted marine salt for it; but this fumigation could not be kept up in rooms were the patients were all confined to their beds. OF THE OPHTHALMIA OF EGYPT. The other endemic, and next to the plague in importance, is the ophthalmia of Egypt; which, though a less fatal, is a more distressing, malady. In Egypt, at particular seasons, it is a most generally-prevailing disease. It is not confined to the human race; the animals of the country, particularly the dogs and camels, are subject to its attacks. Travellers (and, if I remember, Volney is one) describe the same disease as prevailing in Syria; and, I am informed, by my friend Dr Short, that, in Persia, ophthalmia is a most frequent and severe disease. In Egypt this disease proved most distressing and obstinate. The French, it was said, sent from Egypt to France 1000 blind men. The number sent home from the English army was very considerable likewise. Of the Indian army, 50 were sent home invalids from blindness; most of whom were from the 10th and 88th regiments.
