Master F., aged 8 years, had a tedious convalescence from a severe attack of diphtheria, which was suddenly interrupted by a very severe attack of paraplegia; the paralysis was almost complete; he could not walk and could stand only when supported by a table or chair. We had him arrayed entirely in white and placed in strong red baths from one to two hours at a time; soon after being placed in the red light he would fall asleep, and a profuse perspiration burst forth, saturating his underclothing; in three weeks he was walking firmly, and in two months was perfectly well. More than two years have since elapsed and he has continued in perfect health.
