Rosetta is not a healthy quarter. It is one of the largest and worst-built towns in Egypt. There is hardly one street in it. There are only narrow dirty lanes, with high houses overhanging each other, and the passage frequently interrupted by houses in ruins. It is, on two sides, surrounded with swamps. The river is in the front, and behind, it is nearly encompassed with burying grounds. The place of the encampment at El Hammed was an unhealthy spot. About half a mile in the rear of it there was a great extent of swampy ground; but there was no choice: it was necessary to encamp where there was water. As a station for the army, Alexandria had every recommendation. It is built on a peninsula which formed the antient harbour, on a fine dry and open situation. Some squares, and several of its streets, are open and spacious; very unlike an African or Asiatic city. Its numerous mosques afforded us large and airy hospitals and barracks. In point of health, the inundation of the water from the lake Maadie was favourable. It insulated Alexandria; but the water was in motion, and at such a distance, that nothing was to be apprehended from exhalation. All the hospitals at first were within the walls of the modern city. The situation of the Pharos is well known to every one. I have said, that it was complained of as a quarter for troops, and with justice. The state of the 61st regiment shewed this. Subsequently to their being removed from it, they were encamped on the outside of the walls. From this period both the sickness and mortality in this corps disappeared. The 10th regiment found Fort Triangulaire a dry, spacious, and airy, barrack. In the fort they had the means of keeping the men constantly in their quarters; they were at some distance from Alexandria, and thus it was in their power to preserve a regular internal economy and prevent drunkenness. When the regiment came to take possession of this quarter they had a numerous sick-list: it decreased daily after they came here; and, finally, the 10th was as healthy as most other regiments. The barracks of the 80th regiment, and of the Bengal volunteer-battalion, were situated close to Fort Triangulaire; and they possessed all the same advantages, but that it was not so easy to confine the men to the barracks. The barracks of the 88th regiment, at Fort Cretan, were dry and airy. Though in a different quarter they possessed nearly the same advantage as Fort Triangulaire, with the disadvantages of the quarters of the 80th regiment.
