In old English law. A stroke or blow from a club or stone; a bruise, contusion, or swelling produced by a blow from a club or stone, as distinguished from "plaga," a wound. Fleta, lib. 1, c. 41, § 3. ICTUS ORBIS (Lat.) In medical lurisprudence. A maim, a bruise, or swelling; any hurt without cutting the skin. When the skin is cut, the injury is called a "wound." Bracton, lib. 2, tr. 2, cc. 5, 24. Ictus is often used by medical authors in the sense of percussus. It is applied to the pulsation of the arteries, to any external lesion of the body produced by violence; also to the wound inflicted by a scorpion or venomous reptile. Orbis is used in the sense of circle, circuit, rotundity. It is applied, also, to the eyeballs, oculi dicuntur orbes. Cast. Lex. Med. ID CERTUM EST QUOD CERTUM REDdi potest.
