To Francis Galton 7 November [1875]
Summary
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].
