weaker. While it preserves the continuous [flow], which is also what happens on water, it would become for us a distinct thing, with other streams from outside. For when the source is abundant and gathered, the part nearest to it is wide, but it lessens as it diminishes. Finally, it slips away to slip away from below and nowhere is the place hollow or otherwise uneven, which would cause an unevenness or diffusion into a width. This is no less true for the air and the flame. For the air is uniform, but the flame does not travel the same way, but rather because of the slope of the places. It is similar, and perhaps no less •/ because so, to what happens with plants. For the growth of these also extends into a thin point. And the sharp motion of the heat occurs until it takes other sources into itself, making the outgrowth of branches from the outside. The opinion also prevents something and takes away the greater part, just like a sound. It does this not by moving, but by remaining quiet. It takes away more and strengthens it all the more, clearly it seems from these [observations] that it flows away from the opinion of Democritus. because the weaker and more distant [parts] are dispersed by air. Enough has been said regarding the shape. Destructions happen by the shaping of the fire, and we must treat, as he said, regarding the shaping the necessary particulars, such as why burning flesh does not burn the stomach, nor the mouth in the same way. Why do some, when taking lamps into their mouths, extinguish them and are not burned? Why do those who handle red-hot spits metal rods used for roasting more forcefully burn less? For this reason, those who walk on fires, among other things they use, say they do this. And why do burns
