In common with the okapi, giraffes have skin-covered horns on the head, but in these animals, which form the genus Giraffa, these appendages are present in both sexes; and there is often an unpaired one in advance of the pair on the forehead.
The sexes are usually separate.
Primary Inslruction.All primary public instruction is free and compulsory for children of both sexes between the ages of six and thirteen, but if a child can gain a certificate of primary studies at the age of eleven or after, he may be excused the rest of the period demanded by law.
The breast or back, of both sexes, is usually tattooed, or rather, scored with rows of hideous raised scars, produced by deep gashes made at puberty.
Stringent rules, too, governed the food of women and the youth of both sexes, and it was only after initiation that boys were allowed to eat of all the game the forest provided.
