Letters Sent, February 7, 1927

February 7th, 1927. The n. Ingraham Company, Bristol, Conn. Dear Sirs: I don't know as we can give you any moro information relative to the Dunn case other than is given in the clipping you sent. Her case came to our attention shortly prior to hor death, and we are inclined to feel that the history of the case hardly justifies attributing her death to "radium poisoning". as a primary cause. It is possible that it may have been a contributing factor, but so little is definitely known relative to Fradium noucrosis" that en opinion is more or less speculative at the best. We have had considerable experimental worle done in the physiology department of the College of Physicians and Surgeons rolative to the poisonous effects of Undark, and at this time the experiments indicate that there is no danger 1f the material is properly handled and the general health of the applicator is good. By the proper handling of Undark, I rofer to the practice which some girls have of pointing the brushes with their lips. We strondo recommend that this practice be forbidden. As you undoubtedly appreciate, an applicator that has a complaint of most any nature is apt, under the present circumstances, to attribute it to #radium poisoning", and we therefore suzgest that it might be well to keep a rather close checl: on the general health of your applicators. Employ only those who are free from any basic physiologicel disorder. This is not a difficult matter, as about all you noed is the blood picture. With these fow simple precautions we do not fool that there is anything hasardous connected with the use or application of Undark. Very truly yours, Vice President. HHBarker :RH
