Regarding the change of features, as between foreign-born (German) parents and their English-speaking offspring, by which the latter's assume a shape which makes the œsophagus predominate over the trachea, it will be as impossible for these children to speak _idiomatically correct_ German as it is for their parents, with whom the trachea predominates over the œsophagus, to speak idiomatically correct English. When my features assume the proper shape for English speech, I cannot produce a single correct German sound, and when they assume the proper shape for German speech, it is as impossible for me to produce a correct English sound. I expect that this statement will be hotly disputed. The measure of our ordinary mode of listening, however, must not be applied to these matters. In some rare instances the difference is so slight that it takes a very acute ear to notice it. CENTRIPETAL AND CENTRIFUGAL While speaking our native tongue our muscles move, our sinews tend, our vessels lean, _our_ blood throbs, and our nerves tingle with the essence of our language in _its_ direction, and not in the direction of any other language. We not only speak and sing our language, but we gesticulate it, we walk it, dance it, write it, think it, smile it, and sorrow in it. Everything we do is done differently from the same thing done by a person speaking another language. The movements of the muscles of a German are centripetal, while those of an Anglo-Saxon are centrifugal. With a German they close in around the mouth; with an Anglo-Saxon they depart from the mouth upward and downward. Hence the broad features of the German _versus_ the elongated ones of the Anglo-Saxon. Look at the old people. The centrifugal action with an Anglo-Saxon even in old age still leaves his form erect, his face serene, scarcely showing a wrinkle, either on his forehead, his cheeks, or around the eyes and mouth. Apart from his bleached hair, he frequently retains a quite youthful appearance. The centripetal action with a German in old age, on the other hand, has a tendency to bend his form and draw it together, and to shrivel up his skin into innumerable wrinkles, so that his mouth often resembles the mouth of a purse drawn close together. This youthful appearance with aged English-speaking people reflects on their customs and their costume, which latter retains much of the tidiness of their younger days. Germans, on the other hand, age soon. This fact is so apparent that they conform their habits and general appearance to their age. They feel old, and unhesitatingly submit to their aged condition. They often appear old when still comparatively young. English-speaking old people, on the other hand, are never too old not to wish to appear young. For the terms "Greis" and "Greisin," which imply a weakened and somewhat helpless condition, there is no corresponding expression in the English language.
