Mr. Barker-11/23/31-2 -
from you contained an unusual amount of barium. For
quite awhile the boys assumed that this was some
inscluble form of zinc sulfide but they have now de-
finitely established the fact that the material con-
sisted largely of barium sulfate and the presence of
this large quantity of barium plus the barium which
they added to protect the radium has very much lengthened
the number of crystallizations.
The other part of your letter, dealing
with possible danger from alpha rays resulting from the
inhalation of radium emanation and the active deposit
of polonium which results therefrom, I shall try to put
in quantitative form in a day or so, some of this ma-
terial and send on my deductions to you.
Finally, let me say that I have seen Mr.
Stevinson several times downtown and that the last
time I saw him he was certainly just as spry and
vigorous as ever; in fact, he was shaking the hand of
one of his farmer customers, a portly woman, with un-
usual vigor and sustained grip.
Very sincerely yours,
Herman Schlundt
