Has heard that FG will write on inheritance. Huxley does not believe in E. G. Balbiani’s views on subject.

Outlines a memoir he will give at the Anthropological Society in which he differs theoretically with Pangenesis.

In London yesterday for Vivisection Commission.

Is revising his chapter on Pangenesis [in Variation, 2d ed.] to allow that gemmules probably multiply in the reproductive organs.

Notes examples of inheritance of acquired characteristics cited by Brown-Séquard.

Doubts that double parentage is necessary for complex organisations.

Sends a proof of his "Theory of heredity" from the Contemporary Review [27 (1875): 80–95; revised in J. Anthropol. Inst. 5 (1876): 329–48]. Welcomes CD’s help and criticism.

Comments on FG’s paper ["A theory of heredity"]. Finds essay difficult to understand. Objects that FG’s theory conflicts with phenomenon of use and disuse. Conflicts also with rarity of bud-variations in nature.

Says he has ordered FG’s article ["The history of twins", Fraser’s Mag. 92 (1875): 566–76; revised in J. Anthropol. Inst. 5 (1876): 391–406].

Responds to suggestions and criticisms CD made to "theory of heredity" [see 10245].

Comments on FG’s paper ["The history of twins"].

CD is "in a passion with the Spectator who always muddles".

Thanks for the peas which arrived in "beautiful order".
