October 15th,1930. Dr. Herman Schlundt, University of Mirrouri, Columbia, Mo. Dear Dr. Schlundt: There are ordinarily two adhesives used for application of luminous materials to clock, watch dials etc., namely - water adhesive and oil adhesive. The base of the water adhesive is gum arabic, and the base of the oil adhesive is gum mastic. I am wondering if you have ever seen in films which are offered for educational institutions anything depicting the action of radium or the rays smitted therefrom - either in the nature of physical, chemical or biological reaction. I would appreciate any information along this line which might enable me to trace down a source of something along this line. Sincerely yours, HHBarker:RH
