and the Strait o? Magalimens. 171 hood, as well as of the island itself of Cape Horn. The eastern part of King Charleds South Land is low, with plains like the Patagonian .coast; but the range of high land crossing the Strait at Port Famine extends down the north side of Admiralty Sound, and, perhaps with some few interruptions, continues to the south-east extremity of the land, at Cape Good Success, which is the south cape of the west side of Strait Le Maire, and there terminates in lofty mountains covered with snow. one of which, called in the charts ' The Sugar-loaf,' is probably four thousand feet high. The eastern shore of King Charles's South Land, towards the south part, is lofty, but near the northern part is very low. The interior is also low. with extensive plains, abounding with guana- coes, some of which were shot by the otiieers of the Beagle within fifty miles of Cape Horn. In.the year 18?8, from the .commencement of January to the middle of August, thg Adventure (the ship I commanded) was at anchor at Port Famine, in the strait Of Magalhaens, in latitude .53 �' south, and 10n. gitudeL70 �'. west .of Greenwich; and during the whole of that time a careful meteorological journal was kept. ']'he temperalure was registered from a very good ther- mometer of Fahrenheit's scale? suspended wi. thin a copper cylin- drical case of nine i0ches diameter, and perforated above and below with holes, to admit a free current of air. The cylinder was fixed to the roof of a shed, thatched with dried leaves to shelter it from the sun, while the sides were open. The barometer (a mountain barometer made by Newman, with an iron cylinder) was hung up in the observatory, five feet above the high-water mark, and both instruments were examined carefully and regularly at the following hours, viz.: six and nine o'clock in the morning, at noon, and at three and six o'clock in the evening. ' The state of the atmosphere was observed daily, by Daniel's hygrometer, at three o'clock in the afternoon. The maximum and minimum temperatures were also observed twice in twenty-four hours, from a Six's thermometer, viz.: at nine o'clock in the morning, and at nine in the evening.
