During speech the head of an Anglo-Saxon remains impassive; there is no perceptible movement except in connection with his lower jaw. Hence his stolid immovability in contradistinction with the mobility and vivacity of a German, whose entire head, often accompanied by his entire body, appears to take part in his speech. These motions, though fundamental with these peoples, vary with locality, individual character, temperament, etc. A German if he keeps his cranium entirely still will be unable to produce a sound; while an Anglo-Saxon will be unable to produce a sound if he should move it as Germans do. A German's power of vocal utterance lies in the flexibility of his cranium; an Anglo-Saxon's in that of his lower jaw. An Anglo-Saxon grinds the teeth of his lower jaw, in anger or in passion, or while masticating food, or under any other circumstances, against those of his upper; a German grinds those of his upper jaw against those of the lower. All motions in connection with vocal utterance on the part of an Anglo-Saxon are of a decidedly larger compass than those of a German; the latter being confined to the slight motions he is able to make with his head, while the former frequently draws down his lower jaw to a very great extent, far more so than a German would be able to draw down his. The "life" with the German is in the upper, with Anglo-Saxons it is in the lower jaw; the former representing the thorax, the latter the abdomen. While the thorax, as already mentioned, with Germans is the predominating vehicle for every performance of life, with Anglo-Saxons it is the abdomen. With Germans the lower jaw is the anvil, the upper the hammer; with Anglo-Saxons the upper is the anvil, the lower the hammer; the action, the life, always being with the hammer. If you watch an American girl chewing taffy you will find her lower jaw going way down, then out, and up again. This is characteristic of the manner in which Anglo-Saxons breathe and speak. The chewing process, owing to the adhesion of the taffy to the teeth, together with the greater flexibility of a girl's jaws, brings out these features more strikingly than under ordinary circumstances. In chewing taffy the lower jaw (the hammer) meets with some difficulty in making its movements; it is therefore lowered as much as possible, so as to be able to more effectually close in with the upper (the anvil). A German girl's movements under similar conditions are restricted, being largely confined to the upper jaw, which cannot be raised to any great extent.
