Feels there is little he could say as a testimonial for HMJ.
Sexual selection, protection.
Asks JT to distribute some circulars about the work of Gustavus Hinrichs of Iowa, whom CD wishes to help.
Admires JT’s Norwich address [to Mathematics and Physics Section, BAAS meeting, Rep. BAAS 38: 1–6] and his Fortnightly Review paper on scientific discovery [7 (1867): 645–60].

Suggests THF write a paper on violets. Asa Gray, once a sceptic, now declares he is convinced whole structure of a flower is adapted for a cross with another individual.
Urges THF not to give up Pangenesis lightly. "It has thrown light on my mind in regard [to] a great series of complex phenomena."
Thanks BDW for extracts about "drumming" [of male Cicada to attract females].
Asa Gray and Hooker doubt that 13–year and 17–year Cicada forms should be considered distinct species. CD is inclined to agree with them.
Suggests observations be made of ratio of females to males in the rarer form.
Thanks SN for the reference about the reindeer, received via Hooker.
CD wishes to ascertain whether there is any relation between the period of development of a character and its transmission to one sex alone.
