Sir:
Would you please send me the composition of
the luminous material which you sell for putting on
dials?
We need this in order to complete our in-
vestigation of the radium dial painting industry.
Would you also furnish us with a list of the firms
to which you sell this material and, if possible,
please send me about one gram of it.
Very truly yours,
