ARE WE GETTING DULLER ?

[To the Editor of THE SPECTATOR.]

Sta,—Dr. Raymond B. Cattell, following the grave revelations of his intelligence test investigations, rightly urges a reduction of fertility among the least gifted quarter of the population and an augmentationl.of it in the better endowed sections. But is he not too optimistic in believing that the large families of the borderline feeble-minded could be checked by an adequate provision of birth-control clinics ? I submit that race deterioration will continue until the surgical methods be made available to poor parents. All young men might be encouraged to marry and have two, three or more children according to their means and health, and then to ask for the simple operation (vasectomy) whose only effect is to cause sterility. But many wives, fearing consequent infidelity, would prefer tte legalisation .of abortion.—I am, Sir, yours
