It may be compared to that principle adopted by modern chemists, that every elementary body has a definite specific rate of gravity; and indeed the simile may be carried farther still, for as the chemist by combining his elements can prepare a new body, having a different specific gravity rate, dependent on the rates of the original elements; so a country composed of a mixture of two races, exhibits a “Suicide Rate” different from the special rates of the constituent races, and intermediate between them. Although it may not be practicable to prove these statements by a direct appeal to figures, because no case can be produced which is not, at any rate to some extent, complicated by considerations of a collateral nature, but yet the more deeply the matter is investigated the more true it will be found to appear. The statistics collected by Wagner and by Œttingen may be consulted in this connection. The changes of rate produced by Race mingling can be studied, not only in countries where the process has been going on for centuries, but also in respect to recent movements of men. When Europeans emigrate, they are found to carry with them to their new home their peculiarities in regard to Suicide: the several races of Germans have a high rate at home, and on examination of the records of a country peopled by emigration, of New York, for instance, we find that the Germans there kill themselves more often than the Anglo-Saxon element, which has in its home a low suicide rate. During the year 1883, in New York there were 151 cases, of these no less than 70 were Germans; now the proportion of Germans in New York is certainly not seven-fifteenths of the population. The Negro races in their original homes shew an avoidance of voluntary death, and they carry this characteristic with them into other lands: in the United States the relative proportion between the number of suicides, in coloured and white men, is about one to eighty. The rate of suicide observable in a race is seen to be curiously associated with stature; the original inhabitants of Germany were tall and fair; these had originally a high rate, and descendants of this race shew the same peculiarity to-day. In proportion as these fair tall Germans infiltrate another country, just as certainly does the suicidal total grow. Morselli states that in Italy the rate increases from south to north, gradually, in proportion as the stature also increases, until the German states are reached. There is, however, another tall fair race, who have a low rate, the Slavonic; on the eastern borders of Hungary where these immigrate, the Hungarian rates are lowered. In Europe the highest proportion of suicide is shewn by the Germanic races, and the two stocks, German and Scandinavian, divide the supremacy for the maximum rate. The ne plus ultra of German purity in race is found in Saxony, and this kingdom has the largest suicide ratio of any country.
