Dr. Walter M. Gilbert,

Washingtion, D. C.

My dear Gilbert:

Here is a little report on my summer's work, and I hope
it will meet your needs. If not, send it back to me and I
will add or modify, just as you may desire.

Incidentally, I am going to add a letter to Dr. Merriam
which I wish you would present to him, and then in the event
he wishes to see me, make an appointment for me.

Truly yours,
[signed] Paul Bartsch,
Curator, Division of Mollusks.
