Experiment 2, By comparing the abfolute heat of the flefh of an oxes hearty with that of the mufcles of the leg, that of the heart feemed to be the leaft• The flefh in both thefe trials was feperated from the tendinous, and other matters, but for want of good thermometers, and other convenien¬ ce^ they were rather crude ejjays than decijjive ex¬ periments, and require confirmation by more accurate trials. In the fecond experiment it mull be remem- beied that the heart ferves chiefly for involuntary motion. That its fenfible heat, during life, is greater than that of the voluntary mufcles (in hot animals) further appears by its fat, which for this fcafon, is made to congeal fooner, or in a greater degree Oi heat, than that of other mufcles ; and tais iSai;0 another argument that the abfolute heat , , of$
