"I have seen the action on Ophrys exactly as you describe and am thoroughly ashamed of my inaccuracy."
Comments on THF’s MS [on fertilisation of scarlet runners]. Suggests publication, though CD anticipated main features ten years before. Is amused at the caution with which THF put his case that the final end [of the contrivances] was crossing distinct individuals.
Will send THF’s paper [on scarlet runners] to Annals and Magazine of Natural History with a note recommending publication [see 6384].
Suggests books on Lobelia.
Informs THF that Annals and Magazine of Natural History will publish his paper [see 6384].
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."
Advises THF that best plan is to investigate the part certain structures play with all plants or orders, instead of describing means of fertilisation in particular plants. Naturalists value observations far more than reasoning.
