Asks JWL to use his influence to forward the appointment of T. H. Huxley to the Examinership in Physiology and Comparative Anatomy at University of London. Gives details of THH’s qualifications.

Has written very strong notes to Lord Overstone and Sir J. W. Lubbock and hopes they will be of service to THH.

Acknowledges receipt of THH’s lecture [unidentified].

Thanks for answer to query. "I see … that there is no hope of comparing the same genus at two different periods, and seeing whether the tendency to vary is greater at one period in such genus than at another period."

Inclined to dispute SPW’s doctrine that islands are generally ancient. Doubts that they are remnants of continents.

Compliments HW's expression for the formula for coefficients of differences of the odd powers of zero. JH busy, but hopes soon to develop demonstration.
