Encloses some notes on Descent [2d ed.]. Discusses CD’s contention [p. 130] that natural selection could not act to increase altruistic behaviour in man; considers that the benefits conferred upon a person exhibiting such virtues would outweigh the threat to survival that such behaviour would pose.
Thanks for letter of sympathy.
Would like to visit in May.
Bones in goose’s wing perfectly normal. Malformation probably due to want of balance in muscles; analogous to club-foot. Injury of the parent not reproduced in offspring, but may have led to disturbance in functions of nerves which control muscles. Would like further study.
Sends CD two specimens of Fuchsia monstrosities.

Sends Ledum, the nectar of which catches many insects.

S. H. Vines’s work on light inhibition of Phycomyces hyphae ["The influence of light upon the growth of unicellular organs" (1878), Arb. Bot. Inst. Würzburg 2 (1882): 133–47] suggests heliotropism in green plants is independent of, and more primitive than, photosynthesis.
Heliotropism in aerial roots.
Frank Darwin’s work.
