XXVII. An attempt to compare and connect the thermometer for strong fire, described in Vol. LXXII. of the Philosophical Transactions, with the common mercurial ones.

Abstract

This thermometer, which I had the honour of laying before the Royal Society in May 1782, has not been found, from extensive experience, both in my manufactories and experimental enquiries, to answer the expectations I had conceived of it as a measure of all degrees of common fire above ignition: but at present it stands in a detached state, not connected with any other, as it does not begin to take place till the heat is too great to be measured or supported by mercurial ones.
