“In their country it rains incessantly; at least from May to January, and even later the rain does not cease entirely. The climate is not cold, but very wet. The traveller, in going from Kaffa to Doko, must pass over a high country, and cross several rivers, which fall into the Gochob.
“The language of the Dokos is a kind of murmuring, which is understood by no one but themselves and their hunters. The Dokos evince much sense and skill in managing the affairs of their masters, to whom they are soon much attached; and they render themselves valuable to such a degree, that no native of Kaffa ever sells one of them to be sent out of the country. As Captain Clapperton says of the slaves of Nyffie:—‘The very slaves of this people are in great request, and when once obtained are never again sold out of the country.’ The inhabitants of Enarea and Kaffa sell only those slaves which they have taken in their border-wars with the tribes living near them, but never a Doko. The Doko is also averse to being sold; he prefers death to separating from his master, to whom he has attached himself.
“The access to the country of Doko is very difficult, as the inhabitants of Damboro, Koolloo, and Tooffte are enemies to the traders from Kaffa, though these tribes are dependent on Kaffa, and pay tribute to its sovereigns; for these tribes are intent on preserving for themselves alone the exclusive privilege of hunting the Dokos, and of trading with the slaves thus obtained.
“Dilbo did not know whether the tribes residing south and west of the Dokos persecute this unhappy nation in the same cruel way.
“This is Dilbo’s account of the Dokos, a nation of pigmies, who are found in so degraded a condition of human nature that it is difficult to give implicit credit to his account. The notion of a nation of pigmies in the interior of Africa is very ancient, as Herodotus speaks of them in II. 32.”
Now those who believe in the Dokos at all, may fairly believe them to constitute a new species.
Other imperfectly known populations may be put forward in a similar point of view.
All existing varieties may be referable to a single species; but certain species may have ceased to exist.—There is a considerable amount of belief in this respect. We see, in certain countries, which are at present barbarous vestiges of a prior civilization, works, like those of Mexico and Peru for instance, which the existing inhabitants confess to be beyond their powers. Be it so. Is the assumption of a different species with architectural propensities more highly developed, legitimate? The reader will answer this question in his own way. I can only say that such assumptions have been made.
Again—ancient tombs exhibit skeletons which differ from the living individuals of the country. Is a similar assumption here justifiable? It has been made.
The most remarkable phænomena of the kind in question are to be found in the history of the Peruvians.
