Chap. 109. Of dry heats, and cold, and of moist heats and colds.
ALL dry heats, and colds, are created, or produced by such manner of motions, as pleating, folding, surfling, crum∣pling, knitting, linking, brading, tieing, binding into a lesse compasse, or space.
All moist heats, and moist colds, are created, or produ∣ced by such manner of motions, as smoothing, planing, stricking, or stretching; but burning heats, are like those motions that prick a sheet of paper full of holes, or dart it, or cut it, but there are infinite of these several kinds of mo∣tions, which make these several heats, and colds, working according to the several degrees, or temperaments of mat∣ter, and the composers of figures, but l onely set these few notes to make my discourse, as easy to my readers under∣standing as I can; for it is a difficulty to expresse several motions, although they be so grosse as to be visible to the optick sense.
