Paper, 'On the working of the harmonic analyser at the meteorological office' by Robert Henry Scott and Richard H Curtis

Description

The authors write: 'On the 9th of May, 1878, Sir [William] Thomson exhibited to the Society a model of an integrating machine, which consisted of a series of five of the disk, globe, and cylinder integrators, which had been devised two years earlier by his brother Professor James Thomson, and a description of which will be found in the “Proceedings of the Royal Society,” vol. xxiv, p. 262. Sir W Thomson’s paper describing this model will be found in vol. xxvii of the “Proceedings,” p. 371; and reference should be made to both these papers for an explanation of the principle of the machine. In the communication last named it is stated that the machine was about to be “handed over to the Meteorological Office, to be brought immediately into practical work.” The model was received at the Office in the course of the month, and was at once set in action; the results of the preliminary trials, when obtained, being referred to a Committee consisting of the late Professor H J S Smith and Professor Stokes, who, on the 5th of July following, submitted to the Meteorological Council a favourable report on the performance of the model.'

Annotations in pencil and ink. Includes six figures of the harmonic analyser.
