    introducing the thermometer, I found the heat of the water was 73°* : confequemly, the united a&ions of both involuntary and voluntary mufcles, dunng minutes time, had generated fo much heat, that befides preferving the temperature of the body at 98, in the air at 59°* fo much had been thrown off from the fur face, that even that fmall part of it, the hand, had communicated fo much heat to one pint of water, as had railed its temperature from 56 to 73°‘ that is, 17°* ; but it feems from Experiment 3. that the involuntary mufcles aionc would have communicated 9°* ; confequemly the the a£hon of the voluntaxy mufcles, had commu¬ nicated the other 8°* If then the aftion of the voluntary mufcles during 15 minutes, geneiated io much heat as railed the temperature of one pint of water from 65 to 730* by the heat thrown off from the hand : how great muff have been the quantity thrown off from the whole iiuta^c, which that mufcular exertion had generated ! But although fo great a quantity of heat is ge¬ nerated by mufcular action, the mufcles themjclves afford not any part of its compofition, but are only the agents, which combine the principles ok which it is cojnpofcd together ; and one effential part
