Discussion of one Year's Observations of Thermometers sunk to different Depths in different localities in the neighbourhood of Edinburgh
Published online by Cambridge University Press: 16 March 2015
Extract
These observations were made, at Professor Forbes's suggestion, at the expense of the British Association. They are still continued, and the present notice contains only a first approximation to the solution of the problems which they are intended to give.
The chief aim of the experiments is to ascertain the progress of Solar Heat in the Crust of the Globe, and has no immediate reference to the question of central heat; the depth to which the experiments extend being inadequate to afford decisive results on that head.
