Unless one’s attention be specially directed to these aberrant hairs, which are extremely common, one would not expect that hairs could be so variously twisted by muscular action beneath them. You may see a tuft of long hair projecting from the plane of the eyebrows towards the inner end, looking like a small horn, and I have measured individual hairs in elderly persons and found many an inch in length and a few an inch and a half. Such a tuft gives a fierce look to the countenance if the hairs are bushy and plentiful. The celebrated Dr. Keate, the flogging Head of Eton, a fiery strenuous person, was noted for the extraordinary long horn of thick hair in his eyebrows, which he appeared to use as a supplementary finger to point to this or that object of his terrifying attention. You may also see a man with a great drooping curtain of hairs overhanging his eyes, half hiding the upper lids and eyes. Another will show at the outer end of the eyebrows a bristling bush of hairs turning upwards in the aggressive manner of Wilhelm II. of evil memory, or of Mr. Roosevelt in former times. Again the outer points of the eyebrow hairs may turn downwards like a cavalry moustache, or the hairs may stand out at right angles as a level shelf. The fashions of these “orbital moustaches” appear to be as numerous as those of the upper lip. A Conflict of Forces. If the eyebrows are studied in the light of the three muscles displayed in Fig. 20 it is seen to contain an interesting congeries of small forces in conflict. (1) The _frontalis_ moves the eyebrow directly upwards. I had a friend once about seventy years old who was a very vigorous, strong-willed man and he spoke with decision and energy. It was most interesting to watch how his frontalis muscle strongly and frequently contracted as he spoke and drew up his eyebrows so that one might, as it were, measure the strength of his expressed convictions by the rate of action of his _frontalis_ muscle! (2) The _corrugator_ draws the skin of the eyebrow inwards to the middle line thus acting at a right angle to the line of the _frontalis_. (3) The _orbicularis_ in the upper part directly opposes the action of the _frontalis_ and in the lower acts “on its own” in closing the lower lid. This little spot is a Hill 60, destroyed at the battle of Messines, and has been the scene of much fighting throughout life, and it bears abiding witness in the twists and curves of the long hairs to the severity of the struggles. These actions of the three contending muscles are involuntary and of a reflex character, and much employed in such habits as those of knitting the brows or in elevating or depressing them, all this being set going and controlled by cerebral action. Incidentally then the preponderance of one or more of these actions over others, as shown in the hair, is evidence, as far as it goes, of the disposition and character of the possessor. So that between the wrinkles and the
