Unpublished paper, 'On the connexion [sic] between the winds of the St Lawrence [Canada] and the movements of the barometer' by William Kelly

Description

Kelly adduces a great number of observations which are in opposition to the generally received opinion that the mercury in the barometer has always a tendency to fall when the wind is strong. During a period of fifteen years passed in the Gulf and River St. Lawrence, he found that the barometer as frequently rises as falls under the prevalence of a strong wind; and that the winds often blow with greater force with a rising than with a falling barometer. He gives a circumstantial account of the progress and course of various gales which fell under his observation during that period, and from which he infers the existence of a steady connection between the prevailing winds of this region and the movements of the barometer, and enters into an inquiry into the mode in which that instrument is affected by them.

Annotations in pencil throughout. Includes an appendix of meteorological readings taken at Montreal and Quebec between 10 January 1834 and 29 December 1835.
