Dr. Horman Schlundt,
University of Missouri,
Columbla, Mo.
Dear De. Schlundt:
Your letter of October 2nd, enclosing
a negative obtained by exposing for 52 days awo specimen
of Mrs. MacDonald's bone - nanely, vertebra and humerus, has
been received.
I think your deduction that from the photo-
graphic effect the vertebra is more activo than the humerus,
secms unquestionable, and Beems to bear out your quantitative
determinations. However, I would be inclined to place more
dependability upon the emanation detormination than upon the
photographic effects.
Sincerely yours,
Vice President.
