...between the heat and mechanical power generated by the electric current, Mr. Joule was led to conclude that the heat required to raise the temperature of a pound of water 1° F., is equivalent to 838 foot-pounds ; and a nearly equal result was afterwards obtained by experiments...

...experiments, except it be MOTION." : According to Joule's reduction of these result«, they indicate that the heat required to raise the temperature of a pound of water one degree Fahr., is equivalent to the mechanical energy represented by 1034 foot-pounds. This number differs...

...was raised to the boilingfrf'int by the heat resulting from the friction. In this manner it was found that the heat required to raise the temperature of a pound of water by 1° F. is equivalent to 1034 times the force expended in raising a pound weight one foot high, or...
