Cincinnati, Ohio, March 16, 1906.
To the Editor:
—In the current issue of The Journal A. W. Balch, Washington, passed assistant surgeon, United States Navy, takes exception to my article on "Dermatitis Venenata," abstracted in The Journal. He says that while I have had Rhus toxicodendron poisoning twice he has had it eighty times. He queries: "Is it possible that the work of Pfaff is not yet known to the profession?" Had he read the original of my article, not the abstract, he would have seen full reference to Pfaff and his work. I should be pleased to read Dr. Balch's experiences with his eighty cases of poisoning from Rhus toxicodendron more fully written up.
