In a case of Chronic bronchial irritation, I used the chromo-disc over the breast, straining a hot sunlight thus concentrated by reflection, through yellow glass. In less than a minute I was able to rubricate the skin. I used it about 15 or 20 minutes each day for several days. The patient felt uncommonly animated and clear in his mental perceptions, and his bronchial difficulties gradually decreased. The same result would, of course, be produced by means of yellow glass without the chromo-disc, by taking a longer time, or even by hot sunlight, by taking a still longer time. The Chromo Lens to be hereafter described is entirely unequalled in the rapidity and power of its action.
