CHAP. X. ANGER. 341 Then imitate the action of the tiger: Stiffen the sinews, summon up the blood, Then lend the eye a terrible aspect; Now set the teeth, and stretch the nostril wide, Hold hard the breath, and bend up every spirit To his full height! On, on, you noblest English." Henry F., act iii. sc. 1. The lips are sometimes protruded during rage in a manner, the meaning of which I do not understand, unless it depends on our descent from some ape-like animal. Instances have been observed, not only with Europeans, but with the Australians and Hindoos. The lips, however, are much more commonly retracted, the grinning or clenched teeth being thus exposed. This has been noticed by almost every one who has written on expression.0 The appearance is as if the teeth were uncovered, ready for seizing or tearing an enemy, though there may be no intention of acting in this manner.

Dr. Piderit (* Mimik,' &c., s. 82) also speaks of the retraction of the xipper lip during rage. In an engrav- ing of one of Hogarth's wonderful pictures, passion is rep- resented in the plainest manner by the open glaring eyes, frowning forehead, and exposed grinning teeth. 10 * Oliver Twist,' vol. iii. p. £45.
