Corpuscle

(kôr'pus-l, 65), n. [Lat. corpusculum, diminutive of corpus, body; Fr. corpuscule, Sp. corpusculo, It. corpusculo, corpuscolo.] 1. A minute particle, or physical atom; one of the very small bodies which compose large bodies, not the elementary principles of matter, but such small particles, simple or compound, as are not dissolved or dissipated by ordinary heat. It will add much to our satisfaction if those corpuscles can be discovered by microscopes. Newton. 2. (Anat.) An animal cell, or cellular anatomical element; as, a blood corpuscle; a lymph corpuscle.
