|Title||Unpublished paper, 'On supra-annual cycles of temperature in the Earth's surface crust' by C P [Charles Piazzi] Smyth|
|Date||2 March 1870|
|Description||Smyth presents and discusses the completely reduced observation., from 1837 to 1869 inclusive, of the four great earth-thermometers sunk into the rock of the Calton Hill, at the Royal Observatory, Edinburgh, by the late Principal Forbes, pursuant to a vote by the British Association for the Advancement of Science. Leaving on one side the several natural-philosophy data which have been investigated from smaller portions of the same series of observations both by Principal Forbes and Sir William Thomson, the author applies himself solely to trace the existence of other cycles than the ordinary annual one, in the rise and fall of the different thermometers. Marked on front as 'Archives Dec 15/70'.|
