To Editors of the Philosophical Magazine and Journal    Sept 21, 1852

Gentlemen,

In writing his remarks on the ‘supposed absorption of heat by a bismuth and antimony joint’, which occur in your last Number,1 Mr. Adie2 appears to have forgotten the experiment of Lenz,3 in which water was frozen at the point of junction, and the Centigrade thermometer sunk to 3.5 degrees below zero.
