Is sending some seeds of sweetpeas, which George [Darwin] said CD would plant for him.
Interested to hear about the peas.
Agrees to write to William Ogle [about twins with crooked fingers].
Describes growth of sweetpeas for experiment.
Thinks CD’s case of twins with crooked fingers may be one from his twin study.
Sends a lecture CD wished to see
and corrects himself about the twins.
Thanks FG for issues of Revue [Scientifique vol. 7, containing lectures by Claude Bernard].
Ogle says twins [with crooked fingers] are his sisters.
Recommends book by M. A. Puvis [De la dégénération des variétés de végétaux (1837)].
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".
Mentions revisions [in Variation, 2d ed.].
Argues with FG’s theory of heredity, defending Pangenesis: "I cannot doubt that every unit of the hybrid is hybridised and sends forth hybridised gemmules."
Outlines in simple form the statistical distribution of inherited characteristics in a theory of "organic units".
