In the department of experimental psychology Germany again took the lead. G. T. Fechner[63] attempted by means of laboratory tests to discover the law of connection between psychical and bodily events. A band of workers arose, and the new science spread to other countries. In our country Sir Francis Galton took advantage of the International Health Exhibition at London, 1884, to install in the exhibition an anthropometric laboratory, in which a few psychological experiments were made on a large number of people, and since then he has frequently made arrangements for similar laboratories. Footnote 63: _Elemente der Psychophysik_, 1860. In nearly all of the larger universities Experimental Psychology is a recognised study, and almost every variety of mental condition is investigated. Professor W. Wundt, in his _Völkerpsychologie_ (1904), has been a master-builder on these foundations. The experiments in psychological laboratories were of necessity confined to subjects readily accessible, who naturally were mainly Europeans or of European descent. A few observations had been made on aliens who, as a rule, had been brought from their native countries for show purposes; but in these cases the observations were made under unfavourable conditions so far as the subject was concerned. With the exception of these very few and unsatisfactory investigations, experimental psychology was mainly concerned with the subjects numbered 2, 3, and 5 in the table on p. 81. A new departure was made in 1898 by the Cambridge Anthropological Expedition to Torres Straits. For the first time trained experimental psychologists (Drs. W. H. R. Rivers, W. McDougall, and C. S. Myers) investigated by means of an adequate laboratory equipment a people in a low stage of culture under their ordinary conditions of life. The foundations of ethnical experimental psychology were thus laid. Professor R. W. Woodworth sums up the conclusions arrived at from his own observations and those of others as follows: “We are probably justified in inferring that the sensory and motor processes and the elementary brain activities, though differing in degree from one individual to another, are about the same from one race to another.”[64] Footnote 64: _Science_, xxxi., 1910, p. 179. Lately an attempt has been made, under the auspices of the Royal Anthropological Institute, to provide travellers with instructions for psychological investigations in the field.
