To Asa Gray 20 April [1863]
Summary
Fears England and U. S. will drift into war; he and AG must "keep to Science".
Thanks for facts on Incas; regrets he has always avoided the case of man.
Has sent his Linum paper [Collected papers 2: 93–105].
Is it true that Ohio has legislated against marriage of cousins?
Can AG explain the invariable angles in phyllotaxy; are they the consequence of packing in the early bud?
Owen’s comments on heterogeny in the Athenæum [28 Mar 1863] have vexed W. B. Carpenter; CD has replied [Collected papers 2: 78–80].
Hopes AG will observe Gymnadenia; John Scott has been experimenting on its fertilisation.
Gives his observation on pollination of Cypripedium.
