The temperature was registered from a very good thermometer (Fahrenheit scale), suspended within a copper cylindrical case of nine inches 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, namely: 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, namely: at nine o'clock in the morning, and at nine in the evening.---The data of this dataset might have been revised during the review process. This might therefore be an old version. To be sure, please check the respective dataset at doi:10.1594/PANGAEA.871480
