A more special cause of sterility in men is one which operates in the case of workers with radium or the Röntgen rays. Several years ago Albers-Schönberg noticed that the X-rays induced sterility in guinea pigs and rabbits, but without interfering with the sexual potency. These observations have been confirmed by other investigators, who have shown, further, that the azoöspermia is due to the degeneration of the cells lining the seminal canals. In men it has been proved that mere presence in an X-ray atmosphere incidental to radiography sooner or later causes a condition of complete sterility, but without any apparent diminution of sexual potency. As Gordon observes, for those working in an X-ray atmosphere adequate protection for all parts of the body not directly exposed for examination or treatment is indispensable, but, on the other hand, the X-rays afford a convenient, painless and harmless method of inducing sterility, in cases in which it is desirable to effect this result. When Bills are passed to ensure the sterility of the hopelessly rotten and racially diseased, and to provide for the education of the child-bearing woman so that she spaces her children healthily, our race will rapidly quell the stream of depraved, hopeless and wretched lives which are at present ever increasing in proportion in our midst. Before this stream at present the thoughtful shrink but do nothing. Such action as will be possible when these bills are passed will not only increase the relative _proportion_ of the sound and healthy among us who may consciously contribute to the higher and more beautiful forms of the human race, but by the elimination of wasteful lives which are to-day seldom self-supporting, and which are so largely the cause of the cost and outlay of public money in their institutional treatment and their partial relief, will check an increasing drain on our national resources. The setting free of this public money would make it possible for those now too heavily taxed to reproduce their own and more valuable kinds. The miserable, the degenerate, the utterly wretched in body and mind, who when reproducing multiply the misery and evil of the world, would be the first to be thankful for the escape such legislation would offer from the wretchedness entailed not only on their offspring but on themselves. The Labour Party, all Progressives, and all Conservatives who desire to conserve the good can unite to support measures so directly calculated to improve the physical condition, the mental happiness and the general well-being of the human race.
