Because of the nature of the injuries probably causing the deaths of these animals and because of the probable geographic source of their bodies, it is believed that the Atomic Energy Commission should be informed of the incident. You were suggested by San. Engr. Director Gordon E. McCallun, Sr. Surgeon Samuel C. Ingraham, II, and the U. S. Public Atomic Energy Commission of whom they know and in whose advice they have confidence. I should like to request that you accept delivery of the file, which you will note carries a classification of "Secret", and see that it is placed in the hands of the person in the Atomic Energy Commission who should receive such information.
