Dear Dr. Sernseborn:

The purpose of this letter is to ask you if you will take part in
the Symposium on Quantitative Biology at Cold Spring Harbor this summer,
The subject is to be "The Relation of Hormones to Development.” TI am
enclosing a tentative outline of the program, showing the scientists
who are being invited at this time. This program has been prepared by
G. W. Corner, L. C. Dunn, 0. Riddle, and W. J. Robbins. The titles
listed in this outline are only suggestions for topics to be discussed.
Authors are entirely free to select their own titles so long as they
fall within the general scope of the topic assigned to the author.

According to the present plan, the Symposium will begin on the
afternoon of June 10 and continue until June 20. The beginning is
timed to come after the meetings of the Endocrinologists on June 8 and
9 at Atlantic City, and the Symposium will end before the 75th Anniver-
sary celebration of the Torrey Botanical Club which begins on June 22
in New York. All papers and prepared discussions will be published as
Volume X of the Cold Spring Harbor Symposia on Quantitative Biology.

To facilitate discussions and to insure prompt publication, all manu-
seripts should be submitted by June 1.

One of the main purposes of the Symposium is to facilitate the
exchange of ideas between workers in borderline sciences. The Symposium
is planned as one unit, with the expectancy that all participants will
be present throughout the whole session. All participants on the pro-
gram will be guests of the Laboratory during the Symposium, and their
families will be accommodated at regular rates if living quarters are
availabie. However, the Laboratory is not in a position to cover tra-
veling expenses.

The Biological Laboratory is offering its facilities for summer
research to all taking part in the Symposium, and would like to have
many members use the Laboratory 4s their research headquarters during
the whole summer or during a part of it. The Laboratory is reasonably
well equipped for research in several branches of piological and bio-~
physical sciences.

I hope that you will find it possible to take part in this yearts
Symposium. If so, I will appreciate it very much if you will fill out
the enclosed sheet and return it to me at your earliest convenience,

Sincerely yours,

“YN | Generee | (over
