ACME, the height or top of anything. The word is Greek, "ἀκμή" (akmē), point, tip; of "ἀκμάζω" (akmazō), I flourish.

Acme is more especially used to denote the height of a distemper; which is divided into four periods by some institution writers: 1) the Arche, the beginning, or first attack; 2) Anabasis, the growth; 3) Acme, the height; and 4) Paracme, which is the declension of the distemper. See DISEASE.
