Cows, cats, pigeons, chickens, give vent to their feelings by sounds. Language, or the expression of one's thoughts, is therefore common to man and the lower animals. Let us see now what light is thrown on the origin of articulate speech, or the peculiar language of Man, by comparing its development in the child with the languages of different races. It must be remembered that intelligent speech depends as much on the development of the brain as of the vocal organs, for Parrots and Ravens can talk. Naturally, then, words are wanting if there are no ideas to give rise to them. Hence the poorness of the languages of savage races, and the simple talk of the child. Further, one hears few verbs, prepositions, or conjunctions, in listening to the prattle of young children: their expressions are almost entirely composed of nouns and adjectives,—thus, "sugar good," "toy nice," and so on. The language of savage nations is equally simple, often not rivaling even that of the children of the civilized. Hence celebrated philologists, like Grimm, Schleicher, Bleek, regard language as progressive, considering the most ancient languages as much more simple than the modern ones. They maintain that language is not an art, but a natural growth arising from the necessity felt by man of having some means of communicating his ideas. According to Schleicher, the most simply constructed languages have been slowly developed out of the natural cries that Man has in common with animals. He considers that, in the lapse of ages, languages experience great modifications, some, indeed, altogether dying out, others becoming so changed that their origin cannot be certainly determined; that, comparatively speaking, language is a recently acquired faculty depending on development of brain and vocal organs; primitive Man having no language excepting the natural cries inherited from his Ape ancestors. Accepting this theory, we have an explanation of the fact that the roots in the languages of the lowest races of mankind resemble the
