Autograph letter signed : Prague, to Erwin Finlay Freundlich, 1911 Sept. 1.

Thanking Freundlich for his letter, in which he laid out an interesting question, and discussing it and Freundlich's research. Noting that the answer to the "interessante Frage" is not easily found because the light refraction by the Sun's atmosphere has to cooperate, and stating that one thing can be said with certainty: if no such deflection [of spectral lines] exists, then the prerequisites of this theory are not applicable. Further stating that these prerequisites, however self-evident they might be, are very audacious. Musing on the ability to conduct the research if we had a larger planet than Jupiter, but noting that nature did not make it easy for us to find out her principles. Mentioning that Einstein was told that similar surveys had been made in Hamburg, and asking for the results from Freundlich's research of and measuring of the planets.
