My correspondents almost unanimously answer in the affirmative to my query, whether the expression of guilt and deceit can be recognized amongst the various races of man; and I have confidence in their answers, as they generally deny that jealousy can thus be recognized. In the cases in which details are given, the eyes are almost always referred to. The guilty man is said to avoid looking at his accuser, or to give him stolen looks. The eyes are said “to be turned askant,” or “to waver from side to side,” or “the eyelids to be lowered and partly closed.” This latter remark is made by Mr. Hagenauer with respect to the Australians, and by Gaika with respect to the Kafirs. The restless movements of the eyes apparently follow, as will be explained when we treat of blushing, from the guilty man not enduring to meet the gaze of his accuser. I may add, that I have observed a guilty expression, without a shade of fear, in some of my own children at a very early age. In one instance the expression was unmistakably clear in a child two years and seven months old, and led to the detection of his little crime. It was shown, as I record in my notes made at the time, by an unnatural brightness in the eyes, and by an odd, affected manner, impossible to describe. Slyness is also, I believe, exhibited chiefly by movements about the eyes; for these are less under the control of the will, owing to the force of long-continued habit, than are the movements of the body. Mr. Herbert Spencer remarks,[1112] “When there is a desire to see something on one side of the visual field without being supposed to see it, the tendency is to check the conspicuous movement of the head, and to make the required adjustment entirely with the eyes; which are, therefore, drawn very much to one side. Hence, when the eyes are turned to one side, while the face is not turned to the same side, we get the natural language of what is called slyness.”
