The fever which we had in Egypt, at different stations and in different seasons of the year, assumed various types. That which, on the outset, prevailed among the Bombay Sepoys, was remittent. At Ghenné, the fever in the 10th regiment was continued; but it very often terminated in hepatitis. At Ghiza, we have said that we suspected contagion as the cause, at first; but, in the end, the disease was clearly kept up by marshy effluvia on Rhoda Island. It assumed a remittent, and sometimes an intermittent, form, when brought down to Rosetta; and many of the cases terminated in dysentery. At El Hammed, a majority of the fevers which occurred were intermittents; but several remittents occurred, and a few cases which had some resemblance to typhus. After October, fever was a disease of rare occurrence. In the last general return for November, fifty cases appear, of which thirty-four were natives of India. The last return in December is much the same, the native corps having a majority of the cases. In the last return of January there appear, of continued fever, twenty-two cases; twelve of whom were Europeans. Of intermittents there were thirty-two cases, and sixteen of them were Europeans. In the general report of the 26th of February the total of fever in the army is only twenty-three, and of them, only six are natives. On the 26th of April, we had only fourteen cases, of which three were natives. In May, fever did not appear in the reports. Though fever, as it appeared in the Indian army in Egypt, at different periods, occurred with some variation; and though particular symptoms called for occasional variation in the treatment; yet, in its general character, the disease was the same, the proximate cause appeared to be the same, and the same general indication was required to be kept in view in the cure. I am inclined to believe, that, under different names, the same fever prevails over the peninsula of India, and over the eastern islands; and, perhaps, I might venture to extend the remark to the countries between the tropics. This fever has been often well described, under the name of the remittent fever of Bengal. Dr Lind, of Windsor, several years ago, gave an excellent and concise account of it in his Thesis. In Bengal, it is known under the name of the pucca fever. In Madras and on the Coromandel coast, it is the jungle fever. At Bombay and on the Malabar coast, it is known under the same name. In the army in the Guzzerat country, to the northward of Bombay, it is this fever which has proved so destructive of late to our army in the field there, opposed to the Mahrattas. In the island of Salsette, near Bombay, it pays an annual visit, on the ceasing of the monsoon, and proves very destructive. In 1801, on one estate, in Salsette, upwards of forty people were attacked with this fever in one night. I have learned from my ingenious friend Mr Christie, surgeon-general of Ceylon, that it was from the same fever,
