My dear Prof. Wolf:-
New York, Doc.
The New York Academy of Sciences holds
every year in March an exhibition of objects relating to the
you
advance in Science during the preceding year. They have
put me in charge of the astronomical exhibit. I am sure
must have some photographs you would be willing to show. If
such is the case, I shall be very glad indeed if you will send
them on to me. Positives on glass are particularly desirable
as we have very good facilities for showing them. I do not
mean lantern slides, but large positives.
With my very best wishes to you all for a merry
Xmas, and a happy New Year, I remain,
faithfully yours
