Kehoe, Kettering Laboratory of Applied Physiology, University of Cincinnati, College of Medicine, Eden Avenue, - CINCINNATI, AYY;". Ohio, - U.S.A. - Dear Dr. Kehoe, t .. Than!: you very much indeed for your kind letter of the 5th June, and the detailed discussion you include on the life of canister masks. I quite appreciate all the points you raise, and agree.that the matter must be,decided rather arbitrarily and individually in the circumstances concerned I was glad to know that you confirmed my belief that a considerable degree of safety had been included in the period of time chosen for the life of each individual mask, and I will suggest, when the next meeting^in reference to the transport of sludge occurs, that if necessary a slightly longer period of exposure can be contemplated if the shortage of canister masks makes this very desirable. : It was very kind of you to write such a detailed letter during a period when you find yourself so busy. I very much look forward to my visit in the Autumn, when I imagine I shall have a considerable amount to leara.. Dr. Phair is soon to come to Northwich, and I have been drawing up an itinerary for his three days' visit, to include something of everything but most especially to enable him and Mrs. Phair to tour round the Welsh mountains and the Derbyshire peak district., I hope they will enjoy their visit. "A -,. . I will most certainly write to you should any other matters arise which create any difficulty for me. With thanks. 001024?
