Thanks WO for information on inheritance of deficient phalanges [Variation 2:73] and for interesting case of the occurrence of anomalous fingers and teeth in twins[Variation 2: 253].

Wishes he had known of the views of Hippocrates, which are almost identical to his Pangenesis hypothesis. CD advances it as provisional, but secretly expects some such view will have to be admitted.

Comments on WO’s paper on Salvia [Pop. Sci. Rev. 8 (1869): 261–73], which he admires.
