^{page 284 note *} The superficies of the base of the peninsula is exactly 1210 yards in length, by 850 in breadth, exclusive of the isthmus.

^{page 286 note *} The town of New Amsterdam, Berbice, is situated within short musket-shot to leeward of a most offensive swamp, in the direct track of a strong trade-wind, that blows night and day, and frequently pollutes even the sleeping apartments of the inhabitants, with the stench of the marshes, yet it had produced no endemic fever worthy of notice, even amongst the newly arrived, for a period of months and years previously to my visiting that colony.

^{page 288 note *} In some ships of our navy, the fresh-water, instead of being put up in casks, has been preserved in bulk, by constructing a large open tank, of tin or lead, at the bottom of the hold, without in the least affecting the health of the crew, though they slept immediately above it. On land, the very same results have been verified under the same circumstances. One of the healthiest officers'-quarters in the West Indies, is the field-officers at Berkshire Hill, St Vincent's, which is built immediately over the garrison water-tank; and a block house at Demerara, similarly situated, was healthier than the other posts on terra firma.

^{page 293 note *} In our own country, an instance of a pure surface, absolutely destitute of vegetation, proving as malarious as any other spot that I know of in England, may be seen at Dungeness, on the coast of Kent. The point of Dungeness, is a tongue of land, appended to the great Romney Marsh, and consists of an extensive bank of shingle or gravel, so dry, loose, and open, that even during wet weather horses sink in it nearly up to the knees. The forts and barracks are at least four miles from what may be called the Mainland, where the grass begins to grow, yet was there no spot of that unwholesome tract of country more prolific of endemic fever during the hot summer and autumn of 1807 than these barracks. In one part of the gravel, but not near the barracks, were some very deep pools, of no great extent, containing a singularly pure pellucid fresh-water.
