Dr. Warren Weaver,
The Rockefeller Foundation,
49 West 49th Street,
New York City.
Dear Dr. Weaver:
I need hardly say that I am very happy to learn from you that the Rockefeller Foundation will provide support (in addition to that of the California Institute) for my researches for three more years. I have delayed answering your letter for two weeks in order that I might he able to tell you that we had already begun the experimental investigation of hemoglobin; we have met with some difficulties in obtaining pure substances, however, and so the investigation is not yet under way. As I have read about the problems of biochemistry I have become more and more enthusiastic about the possibilities of the application of our methods.
Dr. Noyes has told me that he heard that you would come West this spring; if so, I hope to see you here, and if not, I shall probably call on you in New York at about the time of the Washington meetings, which I hope to attend.
Very sincerely yours,
LP:M
