A Philadelphia professor, it is reported, recently called attention to the fact that in his experience the skin of the negro becomes white under the influence of x-rays. We have not mastered the question of the origin of pigmentation in the human or other species, and are, therefore, not surprised at any such development. It would be interesting to know how further experiments in this line will result. An ambitious New Jersey physician, it is said, is taking negro babies at birth, and by the use of the light treatment hopes to be able to affect their future color. We anxiously await the outcome of the attempt on the part of science to solve the race problem.
