Dear Sir,-
In the Journal of the American Medical
Association, September 26, 1925, an article appears by
Hoffman dealing with Radium (mesothorium) necrosis appear-
ing in employees of a radium plant in Newark, N.J. I assume
this was your plant; if not please advise me. I want to
get in touch with the Management.
In discussing the composition of the luminous
paint used by employees, Hoffman says it contained a minute
quantity of Radium. In a foot note, however, he says that
mesothorium was used in the composition of the paint: on
March 10th, 1926, he confirms this in a letter to myself.
On March 22nd, 1926, Cameron of Pittsburg
writes me "That all cases reported have been workers in mesothorium".
On April 23rd, 1926, DeWitt material P. Sixbey of your
organization, writes me that the luminous metal "contains mostly
radium." Obviously these statements are not all right.
I may have something to say about this matter
in Victoria in June, hence my desire to know the facts, no more
and no less.

In the same Journal, December 5th, 1925, Martland
states that deleterious effects may follow the intravenous in-
jection of radium. I wrote himself, Conlon and Kuef, asking
what authority they had for this statement but SO far have
had no reply.
If Sixbey's statement is correct, please give
approximately the percentage of radium in the luminous paint
in use in your factory. It will be gratifying if the view of
Hoffman and Cameron can be established and it can be demonstrated
that mesothorium and not radium was at fault. I am going slow
on intravenous work myself until this point is cleared up.
Yours truly,
Hughmarkey
