From Arthur Cayley to G. H. Darwin 7 December 1878

Dear M^r Darwin,

I distrust myself very much indeed in any question relating to a tidally distorted body—& doubt whether I shall be able to help you—but if you will send me enough to show how the contradictory arise, I will try & see if I can make the point out—

Believe me yours very sincerely | A. Cayley

Cambridge 7^th. Dec. 1878.
