Delighted to have cloud of darkness removed by CW’s paper on phyllotaxy [Mem. Am. Acad. Arts & Sci. n.s. 9 (1867–73): 379–415].

Has heard that Mivart will answer CW’s pamphlet [Darwinism (1871)].

Thanks correspondent for an interesting paper [unspecified] and his kind remarks about CD’s work.

CD had forgotten Auguste Comte’s "striking observations" on relations of man to lower animals.

Orders books: J. R. Leifchild, The higher ministry of nature (1872);

Hermann Müller, The application of the Darwinian theory to flowers [(1872?), reprint from Am. Nat. 5 (1871): 271–97];

and a review by J. B. Hunter.

Thanks FCD for suggested deletions in MS of Expression. Declines offer from FCD to examine proofs also.
