And so is the zoological; provided that we make concessions in the way of language. Let certain pairs have been created with the capacity but not the gift of speech, so that they shall have learned their language of others. Or let all, at first, have been in this predicament, and some have evolved speech earlier than others—a speech eventually extended to all. It is not easy to answer such an argument as this.

The multiplicity of protoplasts is common ground to the zoologist and the human naturalist, although the phænomena of speech and society give the latter the larger share. The same applies to the doctrine of development. The fundamental affinity which connects all the forms of human speech is valid against the transcendentalist only when he assumes that each original of a species of Man appeared, as such, with his own proper language. Let him allow this to have been originally dumb, and with only the capacity of learning speech from others, and all arguments in favour of the unity of species drawn from the similarity of language fall to the ground.

The eighth doctrine is little more than an exaggeration of the seventh. The seventh will not be noticed now, simply because the facts which it asserts and denies pervade the whole study of ethnology, and appear and re-appear at every point of our investigations.

All known varieties may be referable to a single species; but there may be other species undescribed.—What are the reasons for believing this? Premising that Dilbo was a slave from whom Dr. Beke collected certain information respecting the countries to the south-west of Abyssinia, I subjoin the following extract:—

“The countries on the west and south-west of Kaffa are, according to Dilbo, Damboro, Bonga, Koolloo, Kootcha, Soofa, Tooffte, and Doko; on the east and south-east are the plains of Woratto, Walamo, and Talda.

“The country of Doko is a month’s journey distant from Kaffa; and it seems that only those merchants who are dealers in slaves go farther than Kaffa. The most common route passes Kaffa in a south-westerly direction, leading to Damboro, afterwards to Kootcha, Koolloo, and then passing the river Erow to Tooffte, where they begin to hunt the slaves in Doko, of which chase I shall give a description as it has been stated to me, and the reader may use his own judgement respecting it.

“Dilbo begins with stating that the people of Doko, both men and women, are said to be no taller than boys nine or ten years old. They never exceed that height, even in the most advanced age. They go quite naked; their principal food are ants, snakes, mice, and other things which commonly are not used as food. They are said to be so skilful in finding out the ants and snakes, that Dilbo could not refrain from praising them greatly on that account. They are so fond of this food, that even when they have become acquainted with better aliment in Enarea and Kaffa, they are nevertheless frequently punished for following their inclination of digging in search of ants and snakes, as soon as they are out of sight of their masters. The skins of snakes are worn by them about their necks as ornaments. They also climb trees with great skill to fetch down the fruits; and in doing this they stretch their hands downwards and their legs upwards. They live in extensive forests of bamboo and other woods, which are so thick that the slave-hunter finds it very difficult to follow them in these retreats. These hunters sometimes discover a great number of the Dokos sitting on the trees, and then they use the artifice of showing them shining things, by which they are enticed to descend, when they are captured without difficulty. As soon as a Doko begins to cry he is killed, from the apprehension that this, as a sign of danger, will cause the others to take to their heels. Even the women climb on the trees, where in a few minutes a great number of them may be captured and sold into slavery.

“The Dokos live mixed together; men and women unite and separate as they please; and this Dilbo considers as the reason why the tribe has not been exterminated, though frequently a single slave-dealer returns home with a thousand of them reduced to slavery. The mother suckles the child only as long as she is unable to find ants and snakes for its food: she abandons it as soon as it can get its food by itself. No rank or order exists among the Dokos. Nobody orders, nobody obeys, nobody defends the country, nobody cares for the welfare of the nation. They make no attempts to secure themselves but by running away. They are as quick as monkeys; and they are very sensible of the misery prepared for them by the slave-hunters, who so frequently encircle their forests and drive them from thence into the open plains like beasts. They put their heads on the ground, and stretch their legs upwards, and cry, in a pitiful manner, ‘Yer! yer!’ Thus they call on the Supreme Being, of whom they have some notion, and are said to exclaim, ‘If you do exist, why do you suffer us to die, who do not ask for food or clothes, and who live on snakes, ants, and mice?’ Dilbo stated that it was no rare thing to find five or six Dokos in such a position and state of mind. Sometimes these people quarrel among themselves, when they eat the fruit of the trees; then the stronger one throws the weaker to the ground, and the latter is thus frequently killed in a miserable way.
