On the meteorology of England during the years 1847, 1848 and 1849

At the commencement of this paper the author states, that during the three years ending December 1849, meteorological observations on a uniform system have been taken at nearly forty different places, situated between the latitudes of 49° and 55°, and between the longitudes of 11/2° east and west of Greenwich, at elevations varying from 30 to 350 feet above the level of the sea. Many of the instruments which have been used he has himself selected, and prior to their use has determined their index-errors ; he has also visited the greater number of the stations, and examined their localities, the position of the instruments, &c.
