It is owing to this wonderful elasticity that Japan, when suddenly confronted by foreign arts and sciences, soon succeeded in building up for herself a vocabulary containing all the new terms, and containing them in self-explaining forms. Thus "railway" is expressed by tetsu-do, which consists of the two monosyllables tetsu (iron) and do (way); "chemistry" by kagaku, or the learning (gaku) of changes (ka); "torpedo" by suirai, or water (sui) thunder (rai); and each of the component monosylables being written with an ideograph which conveys its own meaning, the student has a term not only appropriate but also instructive. Hundreds of such words have been manufactured in Japan during the past half-century to equip men for the study of Western learning, and the same process, though on a very much smaller scale, had been going on continuously for many centuries, so that the Japanese language has come to embody a very large number of Chinese words, though they are not pronounced as the Chinese pronounce the corresponding ideographs. Yet in spite of this intimate relation, re-enforced as it is by a common script, the two languages remain radically distinct; whereas between Japanese and Korean the resemblance of structure and accidence amounts almost to identity. Japanese philologists allege that no affinity can be traced between their language and the tongues of the Malay, the South Sea islanders, the natives of America and Africa, or the Eskimo, whereas they do find that their language bears a distinct resemblance to Manchu, Persian, and Turkish. Some go so far as to assert that Latin, Greek, and Sanskrit are nearer to Japanese than they are to any European language. These questions await fuller investigation. PHYSICAL CHARACTERISTICS OF RACES The Japanese are of distinctly small stature. The average height of the man is 160 centimetres (5 feet 3.5 inches) and that of the woman 147 centimetres (4 feet 10 inches). They are thus smaller than any European race, the only Occidentals over whom they possess an advantage in this respect being the inhabitants of two Italian provinces. [Baelz.] Their neighbours, the Chinese and the Koreans, are taller, the average height of the northern Chinese being 168 centimetres (5 feet 7 inches), and that of the Koreans 164 centimetres (5 feet 5.5 inches). Nevertheless, Professor Dr. Baelz, the most eminent authority on this subject, avers that "the three great nations of eastern Asia are essentially of the same race," and that observers who consider them to be distinct "have been misled by external appearances." He adds: "Having made a special study of the race question in eastern Asia, I can assert that comity of race in general is clearly proved by the anatomical qualities of the body. In any case the difference between them is much smaller than that between the inhabitants of northern and southern Europe."
