Observations, 'The absolute direction and intensity of the Earth's magnetic force at Bombay [Mumbai, India]; and its secular and annual variation' by Charles Chambers
Reference number: AP/55/2
Date: 1871
Description
The observations discussed in this paper were taken at the Colaba Observatory between 1867 and 1870, and consist of observations of dip, declination, and horizontal intensity. The absolute observations were taken at a height of 38 feet above the ground; and by comparing them with observations taken with differential instruments at a height of six feet above the ground, they are shown to indicate distinctly a diminution of terrestrial magnetic action with increase of height, with respect both to secular variation of declination and horizontal force, and to diurnal inequality of horizontal force.
Marked on front as 'Archives Jan 7/75'.
Subject: Magnetism
Received 26 October 1871. Read 25 January 1872.
These observations were published in volume 166 of Philosophical Transactions as 'The absolute direction and intensity of the Earth's magnetic force at Bombay, and its secular and annual variations'.
