Turning now to the evolution of speech, the preanalytic stage of sign language was, obviously, accompanied by an emotional gabble', due to the (Darwinian) sympathy of movement between man's hands and mouth. As man acquired the art of symbolizing animals, men, women, bodily actions, relative positions, sizes and other qualities, ete., namely, by drawing symbols of them on a flat surface, he would equally acquire the art of symbolizing these elements by bodily pantomime (including in this the art of outlining in the air) as educated Chinese toto indicate that our present powers of analysis and of separate symbolic zation of the elements out of which day draw ideographs to be read by a Chinese who speaks a different dialect but uses the same method of our general impressions are composed, may be a comparatively recent acquisition of mankind. It also seems possible that the acquisition of thi power may be closely allied to what we call civilization', Assuming that the development of true speech arose from primitive man's acquisition of the power of analysing his environment (as presented to him by his various senses) and of symbolizing the component parts in units and categories—equivalent to our parts of speech'—how did this process begin?
Perhaps the evidence of primitive man's artistic skill, for example, in his early cave drawing, sculpture and modelling, may give the clue.
