it is worthy of notice that, at the present day, or at any rate very recently, there were races of savage men inhabiting this earth who possessed no language at all, and could not, on account of their mode of living, be placed on a higher intellectual level than the higher apes; while we have the authority of the leading philologists of the times in support of the fact that the monosyllabic cries of some of the lower human tribes are quite within the grasp of the ape’s voice. Human beings have been discovered in wild and hitherto unexplored regions who have not the remotest idea of what we should term civilisation. They lead a wandering and useless life, sleeping at nights, not in huts, nor in caves, but squatting among the branches of tall trees, where they are placed out of the reach of savage animals. They do not appear capable of expressing their thoughts in sentences, but make use of exclamatory grunts, which serve the purposes of speech quite sufficiently for their limited requirements; and their general appearance approaches to a remarkable extent that of the higher apes, in that they are almost completely covered with hair, possess a dirty brown skin, short legs, long arms, and full abdomens, can pick up stones, sticks, etc., with their toes as well as their fingers, and show few if any signs of intellectual powers. Let any one visit the Zoological Gardens, in London, and carefully observe the apes exhibited there, and then say whether there is a vast difference between some of them and the human beings who answer to the above description. One need but visit the travelling menagerie of Messrs. Edmunds, and view their “missing link,” an excellent sample of the chimpanzee troglodyte, to see that the difference between man and the lower animals is one only of degree, quite as much as regards intellect as bodily form. I once saw exhibited in the _Jardin d’Acclimatation_, in Paris, a lot of Patagonian or Fuegan (I forget which) natives, who were very little superior intellectually to the chimpanzee. They were stark naked, in a wretchedly dirty condition, and appeared quite incapable of anything like sustained mental effort. But these are by no means the lowest among the human species. In conclusion, I need only re-state my opinion that all so-called living things are but products of the development of protoplasm, whether belonging to the animal or vegetable kingdoms; that this protoplasm possesses the property of vitality, or the power of perceiving stimuli of various kinds and responding to them by definite movements; that the phenomena of mind are but functional manifestations of this protoplasmic development; and that the highest intellectual product of the human mind exists and has existed from eternity in a state of latent potentiality in every atom of protoplasm, as well as in every particle of matter in the universe.
