Sir C. Bell remarks,[26] that "horror is full of energy; the body is in the utmost tension, not unnerved by fear." It is, therefore, probable that horror would generally be accompanied by the strong contraction of the brows; but as fear is one of the elements, the eyes and mouth would be opened, and the eyebrows would be raised, as far as the antagonistic action of the corrugators permitted this movement. Duchenne has given a photograph[27] (fig. 21) of the same old man as before, with his eyes somewhat staring, the eyebrows partially raised, and at the same time strongly contracted, the mouth opened, and the platysma in action, all effected by the means of galvanism. He considers that the expression thus produced shows extreme terror with horrible pain or torture. A tortured man, as long as his sufferings allowed him to feel any dread for the future, would probably exhibit horror in an extreme degree. I have shown the original of this photograph to twenty-three persons of both sexes and various ages; and thirteen immediately answered horror, great pain, torture, or agony; three answered extreme fright; so that sixteen answered nearly in accordance with Duchenne's belief. Six, however, said anger, guided no doubt, by the strongly contracted brows, and overlooking the peculiarly opened mouth. One said disgust. On the whole, the evidence indicates that we have here a fairly good representation of horror and agony. The photograph before referred to (Pl. VII. fig. 2) likewise exhibits horror; but in this the oblique eyebrows indicate great mental distress in place of energy.

Horror is generally accompanied by various gestures, which differ in different individuals. Judging from pictures, the whole body is often turned away or shrinks; or the arms are violently protruded as if to push away some dreadful object. The most frequent gesture, as far as can be inferred from the action of persons who endeavour to express a vividly-imagined scene of horror, is the raising of both shoulders, with the bent arms pressed closely against the sides or chest. These movements are nearly the same with those commonly made when we feel very cold; and they are generally accompanied by a shudder, as well as by a deep expiration or inspiration, according as the chest happens at the time to be expanded or contracted. The sounds thus made are expressed by words like _uh_ or _ugh_.[28] It is not, however, obvious why, when we feel cold or express a sense of horror, we press our bent arms against our bodies, raise our shoulders, and shudder.
[28] See remarks to this effect by Mr. Wedgwood, in the Introduction to his `Dictionary of English Etymology,' 2nd edit. 1872, p. xxxvii. He shows by intermediate forms that the sounds here referred to have probably given rise to many words, such as _ugly, huge_, &c. _Conclusion_.--I have now endeavoured to describe the diversified expressions of fear, in its gradations from mere attention to a start of surprise, into extreme terror and horror. Some of the signs may be accounted for through the principles of habit, association, and inheritance,--such as the wide opening of the mouth and eyes, with upraised eyebrows, so as to see as quickly as possible all around us, and to hear distinctly whatever sound may reach our ears. For we have thus habitually prepared ourselves to discover and encounter any danger. Some of the other signs of fear may likewise be accounted for, at least in part, through these same principles. Men, during numberless generations, have endeavoured to escape from their enemies or danger by headlong flight, or by violently struggling with them; and such great exertions will have caused the heart to beat rapidly, the breathing to be hurried, the chest to heave, and the nostrils to be dilated. As these exertions have often been prolonged to the last extremity, the final result will have been utter prostration, pallor, perspiration, trembling of all the muscles, or their complete relaxation.
