A descriptive catalogue of the Natal contribution to the International Exhibition of 1862

The Rhinoceros is only seen about the banks of the inland rivers; but it must still be very plentiful, to judge from the number of horns that enter the colony. Every store abounds with specimens of them. Twelve hundred horns, worth six hundred pounds sterling, are exported annually from Natal.
[At the International Exhibition in London]
Nos. 125 and 138 shows specimens in all their varieties. 125c is the Horn of the Black Rhinoceros; 125n and 138 are very fine specimens in regard to size.
Most of the African rhinoceroses have two horns arranged as in the double specimen exhibited. The horns are solid appendages, and are fixed upon strong arches of bone provided for their attachment; the foremost upon the nasal bones, and the hindmost upon the frontal bone.
