Dear Mr. Barker:
Will you send me several copies of the article by you
and Dr. Schlundt which recently appeared in the American Journal of
Roentgenology and Radium Therapy. It may interest you to know that I
examined some people for the Federal Trade Commission and found two out
of three to be radio-active.
Referring to a remark in your paper concerning calcium
metabolism I might say that in eliminating metals from the body you do
not get a corresponding elimination of calcium. What seems to effect
calcium metabolism also affect the metals. The parathormone is used in
lead poisoning cases where it acts similarly to the manner that it does
with radium. Just now I am trying a n easier method and am sending some
figures to Dr. Schlundt for his comments.
Yours sincerely
