"The only kind of antilope found on this continent. It differs from all the other members of the tribe in several aspects, and especially in having prong or branch to the horns. The horns rise perpendicularly from the skull till within two or three inches of the points, where they curve suddenly backward and inward, forming a small hook like those of the chamois." — S. G.

"The Death's-head Moth is the European Acherontia Atropos, a hawk-moth with markings on the thorax resembling a skull or death's head, hence the name. It flies after sunset and emits peculiar sounds somewhat resembling the squeaking of a mouse, produced by the friction of the proboscis against the inner striated coatings of the palpi. It attacks beehives, scatters the bees, and steals the honey."&mdash;(Charles Leonard-Stuart, 1911)

"The Gorilla is a celebrated anthropoid ape, generally belived to come nearer than any known one to man. The height is about 5 feet, almost the same as man. On the other hand, the greatest capacity of the gorilla's brain is only 34 and one half cubic inches, the least 23 against 62 in the least capacious human skull, and 114 in the greatest. The low facial angle also, and the abundant hair, with the extraordinary breadth of the chest, diminish the resemblance. The last mentioned characteristic imparts to the animal a colossal strength. It is a native of Lower Guinea and the interior of equinoctial Africa."—(Charles Leonard-Stuart, 1911)

"Any piece of felt; more especially, a skull-cap of felt, a hat. These seems no reason to doubt that felting is a more ancient invention than weaving, not that both of these arts came into Europe from Asia. From the Greeks, who were acquainted with this article as early as the age of Homer, the use of felt passed together with its name to the Romans. Its principal use was to make coverings of the head for the male sex, and the most common one was a simple skull-cap." &mdash; Smith, 1873

"Thor, the thunderer, Odin's eldest son, is the strongest of gods and men, and possesses three very precious things. The first is a hammer, which both the Frost and Mountain giants know to their cost, when they see it hurled against them in the air, for it has split many a skull of their fathers and kindred. When thrown, it returns to his hand of its own accord. The second rare thing he possesses is called the belt of strength. When he girds it about him his divine might is doubled. The third, also very precious, is his iron gloves, which he puts on whenever he would use his mallet efficiently." &mdash;Bulfinch, 1897
