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 moun- tain barometer made by Newman, with an iron cylinder) was hung up in the observatory, five feet above the high-water mark, and both instruments wei'e 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.
