Dear Sir:

In the absence of the Secretary, I am authorised to acknowledge the receipt of your inquiry of April 24, and to inform you that no observations of the heating effect of the stars have been made at the Smithsonian Astrophysical Observatory. I am able to refer you, however, to the work of Professor E. F. Nichols (now of Columbia University, New York City), done at the Yerkes Observatory and published in The Astrophysical Journal, Volume XIII, Page 101, 1901.

Very respectfully yours. | [signature illegible]

Assistant in charge of Office.

Doctor Alfred R. Wallace,

Broadstone, Dorset,

England
