XXXIII.—Description of a New Self-Registering Barometer
Published online by Cambridge University Press: 17 January 2013
Extract
Although many proposals have been made to obtain a series of hourly meteorological observations by mechanical means, this desideratum has not, from various causes, been completely attained. The chief obstacle to be overcome, in such self-registering instruments, is the great amount of friction, which necessarily vitiates all the results, more especially in delicate instruments, such as the barometer and thermometer.
Dr Robert Hooke was the first to propose a self-registered series of meteorological observations, by an instrument, which he quaintly called a Weather-wiser; but no further notice is taken of this contrivance than a short description in one of his tracts, bearing the date 5th December 1678, which would lead us to believe that the instrument was never used. The late Alexander Keith, Esq. of Ravelston also proposed a similar contrivance, a description of which is contained in this Society's Transactions, Vol. 4th. This contrivance, from the constant friction excited by the marker on the revolving paper, seems likewise to have been abandoned.
