its removal from the living animal, and while yet soft at its base, where it had been attached to the skin. Its shape was nearly straight, then slightly contracted, forming a very obtuse angle, and afterwards swelling out like the bulb of a bristle, to its termination. It was laterally flattened throughout its entire length, which did not amount to quite three-eighths of an inch, of horn colour, and nearly black at the tip. Its connexion with the skin must have been very slight, which accounts for its usual absence in stuffed as well as living specimens. This does not depend upon age, as it was found alike in the Paris Lions, of considerable size, as well as in the Zoological Society's Lions, very small and young; nor did it depend upon sex. It appears to be occasionally present in the Leopard; and, in both Lion and Leopard, it is seated at the extreme tip of the tail, and is altogether unconnected with the terminal caudal vertebra; not fitted on like a cap, but rather inserted into the skin. The use of the prickle, however, it still remained difficult to conjecture; but that its existence was known to the ancients is proved by the Nimroud sculptures in the British Museum, in an exaggerated representation of the claw, in support of this curious fact in natural history. The existence of the claw has been proved by Mr. Bennett; and "it is no small gratification to be able now to quote in evidence of the statement of Mr. Bennett, and of his predecessor. Didymus, of Alexandria, the original and authentic document, on the authority of the veritable descendants of the renowned hunter Nimroud; which any one may read who will take the trouble to examine the sculptured slab in the British Museum."[8]
