Darwin-Hooker Letters : Letter from Hooker, J. D. to Darwin, C. R. on 16 Sept 1864 : 243r
'Hooker, J. D.'
Rejoices that Darwin is beginning 'the book of books', Variation. Suggests that changes in colour of pollen, stigma, and corolla, as Scott reports in his Primula paper, may be related to changes in the insects required for pollination. Supports Gärtner translation by Ray Society. Comments on recent addresses by Lyell Rep. BAAS 34 (1864): lx–lxxv, Bentham Proc. Linn. Soc. Lond. 8 (1864): ix–xxiii, and Murchison Rep.
