Summary

Thinks JDH is a bit hard on Asa Gray.

Bates’s letter is that of a true thinker. Asks to see JDH’s to Bates. Point raised in it is most difficult. "There is one clear line of distinction; – when many parts of structure as in woodpecker show distinct adaptation to external bodies, it is preposterous to attribute them to effect of climate etc. – but when a single point, alone, as a hooked seed, it is conceivable that it may thus have arisen." His study of orchids shows nearly all parts of the flower co-adapted for fertilisation by insects and therefore the result of natural selection. Mormodes ignea "is a prodigy of adaptation".
