Would like CD to write a paper on the results of geese experiments; hopes CD will not object to his doing the same despite the variance of their conclusions [see F. B. Goodacre, "Question of identity of Chinese and domestic goose", Proc. Zool. Soc. Lond. (1879): 710–12 and CD’s "Fertility of hybrids from the Chinese and common goose", Collected papers 2: 219–20].
