To the Editor:
—In The Journal, June 2, p. 1588, is an article by Dr. Albert Strickler on "The Value of the Toxin (Antigen) of Rhus Toxicodendron and Rhus Venenata." This material is considered in its relation to treatment during the attack and to immunization. A table of cases treated by thirty-five physicians sets forth the records of 356 patients, though nineteen of the physicians reported less than five cases each. "In the vast majority of cases, improvement was noted twenty-four hours after the institution of this mode of treatment." In the second paragraph of the "comment," bearing on desensitization, occurs the statement, "It is incapable of doing harm." With this remark I beg to differ. In the early summer of 1921, a medical student came to the Jefferson Hospital Skin Dispensary with this history: He had had an attack of dermatitis venenata and had been treated by Dr. Strickler.
