Gentlemente We believe you will agrea that the article sent you under July 12th on the subject of "Relio Activa listerial an Industrial Hasard?", shows that Dr. Tinn has gono into this subject more thoro- ughly them anyone olse. His findings, hozevor, are not final; and it has occurred to us that since this subject is so importent it yould be most dosirable for both the and usero of luminous material to havo the study and esperinents carried on over a much greater period of time. of course, to do this requires a grost deal of timo and some money and tre wonder if you, as a large usor of luminous naterial, would be willing to contribute say $500. or $1,000., or eny rensonable amount, towards a fund that might permit of a continuation of this splendid works It is estimated that a minimun of $5,000 will be necessary.
