FootnoteHEAT, in phylology, one of the forecary qualities of bodies, produced by fire, and opposed to cold.

FootnoteUnder the article fire, we considered the fun as the principal source of heat upon the earth's surface, and the conifers of the earth and atmosphere: with out this, all the hotles open our globe would doubt- left grow right, lifelife, and feed... It is this that flies within them, as the main frying of their actions. Hence vegetation and animalizations are evidently pro- mored; and hence the ocean and the atmosphere co- timese in a fluid flare.

FootnoteHeat its us is properly a fanitation, excited by the action of fire, or is it the effect of fire on our organs of feeling. Hence it follows, that what we call heat is a particular idea or modification of our own mind, and not any thing exfiling is that you in the body that occasions it. Heat, frys Mr Locke, is no more in the fire that burns the finger, than pain is in the needle that pricks it. In effect, heat in the body that

Footnotegives it, is only motion ; and in the mind, only a par- ticular idea.

FootnoteHeats the hot body, according to 'S Gravefunde, is an agitation of the parts of the body, made by means of the fire contained in it: by fuch an agitation a mo- tion is produced in our bodies, which excite the idea of heat in our mind! To this heat in respect of us is nothing but that idea, and in the hot body nothing but motion. If fuch motion expel the fire in right liner, is gives us the idea of light; it in a various and irregular motion, only heat.

FootnoteHeat, with respect to our conditions, or the effect produced on us by a hot body, is eliminated by ir reda- tion to the organ of feeling; no object appearing to be hot, unless it heat exceed that of our body. When the fans things to different perform or at different times to the flame perlon, full appear both hot and cold. The degree of heat is measured by the expansion of the air, or spirit in the thermometer.
