Dear Dr. Heidelberger:
I am sending enclosed my manuscript on the structure and properties of antibodies. I would be glad to have your opinion of the manuscript, and especially any suggestions about its improvement. The manuscript has been submitted to Lamb for publication in the Journal of the American Chemical Society, with the suggestion that I might want to revise it somewhat before publication.
With best regards, I am
Sincerely yours,
Linus Pauling
P.S. Are my references to your work all right?
