Paper, 'On the connexion between the state of the Sun's surface and the horizontal intensity of the Earth's magnetism' by Balfour Stewart

Description

Stewart writes: 'The late John Allan Broun, in a paper published in the “Transactions of the Royal Society of Edinburgh” (vol. xxii, Part 3), has compared together the daily changes of the Earth’s horizontal magnetic force at the four stations—Makerstoun (Scotland), Trevandrum (India), Singapore, and Hobarton, and has come to the following conclusions:— (1.) The daily mean horizontal force increases at the same time at all the stations, and diminishes at the same time at all the stations. (2.) The proportional amounts of increase and diminution at the stations are not very different from each other.'
