“ When the antlers are freed from the velvet—a process usually assisted by the animal rubbing them against tree stems or boughs—they have a more or less rugose surface, owing to the grooves formed in them by the nutrient blood-vessels. Although a few living species have the antlers in the form of simple spikes in the adult male, in the great majority of species they are more or less branched; while in some, like the elk and fallow-deer, they expand into broad palmated plates, with tines, or snags, on one or both margins. ”

“ The antlers are large and curve forwards, giving off an upright snag near the base, and several vertical tines from the upper surface of the horizontal portion. As we proceed southwards from the northern United States, deer of the white-tailed type decrease steadily in size, till in Central America, Peru and Guiana they are represented by animals not larger that a roe-buck. The most convenient plan appears to be to regard all these degenerate forms as local races of the white-tail, although here again there is room for difference of opinion, and many naturalists prefer to call them species. ”

“ 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. The pedicles are always covered with skin well supplied with blood-vessels ”
