A year ago I1 published a note on the use of benzoyl peroxide as a dusting powder in the treatment of poison ivy intoxication, stating that this was a harmless substance, that theoretically it should be of value, being an active oxidizing agent and absorbent and, above all, acting as a local anesthetic which might be of great value in the relief of itching. Benzoyl peroxide has now been given a trial in possibly 100 cases with about the results that might be expected. Unbelievable relief within fifteen or twenty minutes after the application of the powder has been observed in several cases and great improvement in the poison ivy lesion itself. Others report only fair results, while still others state that benzoyl peroxide is entirely ineffective.
The apology that I should like to make is not one regarding the therapeutic value of this substance but for having allowed
