In reopening this department, I have, first of all, the thought in mind of discussing some questions which will prove of importance to the greatest number of readers. Looking over my files and judging from the letters previous! y received, the most popular subject in the minds of those who took advantage of this service was Colitis, of Ptosis. I say popular for the reason that I was “swamped” with letters seeking information on this particular subject. Furthermore, regardless of the fact that· I had covered this form of illness month after month in this department, the letters continued to pour in, seeking further advice. Evidently, those who read these pages could not see any similarity in their cases and the cases previously discussed herein.
