Gentlemen:
Please forward to the Army Medical Museum at your earliest convenience, with bill: 1 Fluorescent screen, 11” x 14”, (tungstate of calcium) for use in contact with plate for lessening time of exposure – the screen to be made as fine as possible to prevent granulation.
Very respectfully,
D.L. Huntington
Deputy Surgeon General, U.S. Army,
In charge of Museum and Library Division.
