. A most useful supplement to that excellent journal Nature

of April 21st is concerned with sunlight treatment in the home. - The doctors who write for it emphasize the fact that ultra-violet radiation is not a cure-all and that the treatment is not without risk. But it has caught the popular imagination. Danger in its misuse there certainly is, as there is peril in the careless handling of a motor-car or in grasping the wrong end of a red-hot poker ; none the less we think that more and more people will switch on, an Alpine, sun in their bedroom, now that mereury-vapour lamps are available -for as low a price as £10. To those who wish to hwie the best expert opinion on the subject, we can recommend last week's Nature.
