There they may learn that Archytas [10] made a dove that flew, that Archimedes made a mirror which kindled fires at great distances and many other remarkable machines, that other men have kindled perpetual fires, and assater hundred more inventions no less amazing.

The rubbing of particles, when occurring quickly, generates heat.

The sense of touch is more material than the other senses; and, as it arises from the solidity of matter, it seems to be related to the earthly element. Sarsi says that no author worth considering, ancient or modem, has ever supposed a comet to be a mere appearance; hence that his teacher, who was disputing only with such men and did not aspire to victory over any others, did not need to remove comets from the company of mere images. Now since a greater or less enlargement depends not upon the material of a telescope but upon its shape, the tube constitutes different instruments when the same material is used but the separation of the lenses is altered.

If you would only sssayer me what this “whatever else” is, I should endeavor to provide it. The primary qualities exist regardless of people, but the secondary qualities would disappear without living creatures to experience them—secondary qualities exist only in the experiencing body.
