Director of the Observatory
where this note is presented.
Dear Sir:
Herewith I take the liberty of in-
troducing to you my young friend, James F.
Koehler, who has been informally associated
with this Observatory in the past. He is
keenly interested in astronomy and would
appreciate the opportunity of seeing such
parts of your institution as it may be con-
venient for you to open to him.
Any courtesy which may be shown him
will be appreciated both by him and any
members of his family who may accompany him,
as well as by myself.
Mr. Koehler is now instructor-elect at
Princeton University.
Accept the assurance of my highest
respect.
Very truly yours
Edwin B. Frost
Director
Kindly return this note to Mr. Koehler.
