The leading characters of antlers are described under Pecora, but these structures may be defined somewhat more fully in the following passage from the present writer's Deer of all Lands:- " Antlers are supported on a pair of solid bony processes, or pedicles, arising from the frontal bones of the skull, of which they form an inseparable portion; and if in a fully adult deer these pedicles be sawn through, they will generally be found to consist of solid, ivory-like bone, devoid of perceptible channels for the passage of blood-vessels.
When the first or a new antler is about to be formed, the summits of these pedicles become tender, and bear small velvet-like knobs, which have a high temperature, and are supplied by an extra quantity of blood, which commences to deposit bony matter.
This deposition of bony matter progresses very rapidly, and although in young deer and the adults of some species the resulting antler merely forms a simple spike, or a single fork, in full-grown individuals of the majority it assumes a more or less complexly branched structure.
