‎First printing of a classic paper in thermodynamics. In this paper Reynolds describes his construction of laboratory apparatus for better measurement of Joule's mechanical equivalent of heat""Reynolds' most extensive experimental work concerned the mechanical equivalent of heat"" specifically, he found the mean specific heat of water (in terms of work) between the freezing and boiling points. The results rank among the classic determinations of physical constants."" (In the paper offered).(DSB XI, p. 393)‎
