Robert A. Kehoe, M.D. The Kettering Research laboratories Cincinnati, Ohio Dear Dr. Kehoe: In 19^3 our Mrs. Lloyd spent two \*eeks at the Kettering Laboratories, studying stipple cell reading. After re turning to Lockport she was able to hare the stipple stain made up in our chemical laboratory and the results were very satisfactory. A recent change in chemists, how ever, has brought about a poorer quality of stain. It would be very reassuring if we co'old make some arrange ment, to purchase the future stock stain from your depart ment. If this can be arranged we shall appreciate hearing from you. 4i Very truly yours I 5 i * Merrill P. Benoit, M.D. Plant Physician MP3:A! \ i KE N17493
