Hobart A. Kehoe, 1.1. D., Laboratory of applied Physiology, University of Cincinnati, Cincinnati, Ohio. Dear Doctor Kehoe: I am in receipt of your letter of February 23d advising me as to your work and studies in the matter of lead poisoning, and further as to the Journals in which your articles may be found. Your letter is of spcial importance to my department, particularly with a view to convincing the officials of our road who have charge of this work that we are dealing with a serious problem. Information that they have had thus far from various sources has been prone to minimize the hazards to which this class cf workers have been subjected. I amdeeply grateful to you for your letter and will appreciate any further assistance you may be able to render us. Very truly yours Chief Surgeon.IVHw.
