Mr. H. H. Barker, Vice President,
United States Radium Corporation,
535 Pearl St.,
New York City.
Dear Mr. Barker:
The gamma-ray electroscope arrived
safely and I want to thank you for kindly lending it to us.
Dr. Sayers thinks it would be a good
thing for us to show this instrument in our exhibit at the
coming Century of Progress Fair at Chicago, but he suggests
that we ought to polish up the brass parts and give it a
coat of black paint. I told him that you would not wish to
have the instrument opened so that its adjustment would be
changed in any way; but he thinks that we could polish up
the brass and apply the coat of paint without opening it up
or changing its adjustment. Would you be willing for us to
do this?
With kind regards, I am
Yours very truly,
James E. Ives
