The climate? though warm, is perfectly salubrious. The range of the thermometer, in the hottest season, is from 78 �86 and in the coldest, from 72 �81% The general winds are from south to east, subject to interruptions from the vicinity of the north-west monsoon, which lasts from January to March. No two seasons have been as yet alike, since the formation of the settlement, but until the present they have never had more than an occasional squall of a few hours continuance from ?he north- ward or westward. The fresh water, obtained from wells dug on the isles, is good, .wholesome, and abundant. The anchorage is safe--the narrow op?ning between the reefs of Hotsburgh and Direction. isles. not affording ingress to any heavy zea, as was experienced during late northerly gale. The channel le?ding into the inner anchorages has only three fathoms and three-quarters at low water, .and is tortuous and narrow ?or nearly a mile. No vessel drawing more than twelve feet water may safely sail in; but ships requiting heaving down, ?c., may be warped for that purpose Into the basin inside of Direction island. There can be, however, no occasion for entering the port beyond the outer anchorage, except for safety in time of war. The intricacy of the entrance is then an advantage. High water is at about half-past four o'clock in the anchorage, on full and change. When the sun is near the equator, the two tides are nearly equal, and rise from three and a half to four feet. When the sun is near the southern tropic, his zenith, or evening, tide rises to from five to five and a half feet, and the morning tide to one and a half and three feet. The contrary happens when he is near the northern solstice. �lII.mNotes respecting the hthmus of Panama. Communicated by J. A. Lloyd, Esq. Extracts from them read 28th of February, and 14th of March, 1831. tI? November, 1827, Mr. Lloyd, who had served for some time viously on General Bolivar's personal staff, received from him a special commission to survey the Isthmus of Pansink, in order to certain the most eligible line of communication across it, whether by road or canal. And the result of his operations, in so far as they regarded the level of the respective seas, and the elevation of the in- tervening Isthmus, has been already published in the Philosophical Transactions for 1830, p. &9.raThe following supplementary infor- mation seems, however, still interesting; and is extracted from Mr. Lloyd's entire notes communicated by him to the Royal Geographical 8ociety? before his recent departure for the Mauritius.
