corpuscles

We often refer to our highways, roads and avenues as “arteries,” as if they carried corpuscles instead of cars, platelets rather than pedestrians.

My senses seemed supersensitive and I was sure I could hear their food going down, their corpuscles moving through their bloodstreams, their alveoli inflating and deflating.

That is, the invisible corpuscles or atoms which, for a Cartesian, constitute light.

Behind the epic variance of natural organisms—tall; short; wrinkled; smooth; green; yellow; brown—there were corpuscles of hereditary information, moving from one generation to the next.

Functionally, corpuscles thus served as atoms, while avoiding the mathematical objection against indivisibility.
