On the horn of the rhinoceros

If we examine the structure of the horn of the Rhinoceros, we find that it is essentially made p of a collection of hairs, that is, a mass of long corneous cylinders, nearly parallel to each other. If then, we define a hair as a corneous cylinder of variable length, we may regard nails, claws, hoofs, conreous horns, quills etc. as merely confluent horns. This horn at its base is evidently fibrous, being rough like the stump of an old brush; it belongs entirely to the skin, being in no way connected with the bones of the skull; so that (as Burchell says in his Travels), it is not imporbable that the animal may have the power of moving it to a certain extent. The length of this horn, measuring its convexity, is 37 ? inches, its circumeference et the base is 21 1/4 inches; its weight 18 1/4 pounds. [locality and species not recorded.]
