They are nomadic hunters and collectors, never resorting to agriculture. They have no domestic animals. Only meat is cooked. They wear no clothing. They use bows and poisoned arrows. Their language is unknown. They live in small communities which centre round a cunning fighter or able hunter. Their dead are buried in the ground. They differ from surrounding Negroes in having no veneration for the departed, no amulets, no magicians or professional priests. They have charms for ensuring luck in hunting, but it is uncertain whether these charms derive their potency from the supreme being, though evidence of belief in a high-god is reported from various pygmy peoples.[303] THE BUSHMEN AND HOTTENTOTS. Towards the south the Negrillo domain was formerly conterminous with that of the Bushmen, of whom traces were discovered by Sir H. H. Johnston[304] as far north as Lakes Nyasa and Tanganyika, and who, it has been conjectured, belong to the same primitive stock. The differences mental and physical now separating the two sections of the family may perhaps be explained by the different environments--hot, moist and densely wooded in the north, and open steppes in the south--but until more is known of the African pygmies their affinities must remain undecided. The relationship between the Bushmen and the Hottentots is another disputed question. Early authorities regarded the Hottentots as the parent family, and the Bushmen as the offspring, but the researches of Gustav Fritsch, E. T. Hamy, F. Shrubsall[305] and others show that the Hottentots are a cross between the Bushmen--the primitive race--and the Bantu, the Bushman element being seen in the leathery colour, prominent cheek-bones, pointed chin, steatopygia and other special characters. In prehistoric times the Hottentots ranged over a vast area. Evidence has now been produced of the presence of a belated Hottentot or Hottentot-Bushman group as far north as the Kwa-Kokue district, between Kilimanjaro and Victoria Nyanza. The _Wa-Sandawi_ people here visited by Oskar Neumann are not Bantus, and speak a language radically distinct from that of the neighbouring Bantus, but full of clicks like that of the Bushmen[306]. Two Sandawi skulls examined by Virchow[307] showed distinct Hottentot characters, with a cranial capacity of 1250 and 1265 c.c., projecting upper jaw and orthodolicho head[308]. The geographical prefix _Kwa_, common in the district (Kwa-Kokue, Kwa-Mtoro, Kwa-Hindi), is pure Hottentot, meaning "people," like the postfix _qua_ (_Kwa_) of Kora-_qua_, Nama-_qua_, etc. in the present Hottentot domain. The transposition of prefixes and postfixes is a common linguistic phenomenon, as seen in the Sumero-Akkadian of Babylonia, in the Neo-Sanskritic tongues of India, and the Latin, Oscan, and other members of the Old Italic group.
