TLS, one page, 8.5 x 11, California Institute of Technology letterhead, February 6, 1931. Letter to Charles H. Chase, in full: "I am writing to acknowledge receipt of your letter of January 26th, and to say that from the standpoint of an experimentalist like myself, and also from that of a theorist like Professor Einstein, the one check on equations which enable us to predict new results lies in the agreement or disagreement of the predicted and observed phenomena. Up to the present, all the new phenomena predicted by relativity equations and experimentally tested have shown agreement within the limits of uncertainty of experiment and prediction. This situation scarcely seems to me to justify such phrases as you use in your discussion of the theory." In very good to fine condition, with a crease to the upper left, and rusty paperclip impressions to the left edge.
