My dear Barker:
I am enclosing a print made from the negative
obtained by exposing for fifty-two days, two specimens of
bone obtained from Dr. Ewing last spring. These bone speci-
mens were from Mrs. MacDonald. One is a section of the
humerus and the other of a vertebra. It seems to me that if
these photographs are at all reliable, the radium content of
the vertebra greatly exceeds that of the humerus. The photo-
graphic effect harmonizes with the radium determinations by
the emanation method which I made last summer. It was found
that the radium content of the vertebra was about twice that
of the humerus, weight for weight.
With good wishes, I remain,
Sincerely yours,
Herman Schlundt
