Dr. F. Failla,
c/o Memorial Hospital,
106th St. & Central Park W.,
N.Y.C.
Dear Dr. Failla:
We have completed the exemination of the
standard radium solution which you gave me one day nt the
Memorial Hospital.
By boiling off the emenation with nitric
aoid we find that the specimen shows 2.5 x 10-8 grams per
cc. While bubbling air through the solution gives us the
value of 2.6 X. 10-8 grams per cc.
Sincerely yours,
Vice Prosident.
