XLVII. Further experiments and observations in an heated room

Abstract

On the third of April, nearly the same party as before, together with Lord Seaforth, Sir George Home, Mr. Dundas, and Dr. Nooth, went to the heated room in which the experiments of the 23d of January were made. Dr. Fordyce had ordered the fire to be lighted the preceding day, and kept up all night; so that every thing contained in the room, and the walls themselves, being already well warmed, we were able to push the heat to a much higher degree than before. In the course of the day several different sets of experiments were going on together; but to avoid confusion, it will be necessary to relate each series by itself, without regard to the order of time; beginning with that series which serves as a continuation of our former experiments.
