Agrees to look over MS.
Describes data relating to variability of Primula elatior.
Encloses Fritz Müller’s letter.
Is exhibiting butterflies in which variations in the female show a finely graded series. Believes dimorphism can be explained by the selection of the extremes of such a series and the consequent extinction of the intermediates.
Thinks the facts in Fritz Müller’s letter could be published.
Recommends August Weismann’s essay on dimorphism ["Über den Saison-Dimorphismus der Schmetterlinge", Studien zur Descendenz-Theorie 1 (1875)]
