From Gaston de Saporta 2 September 1876
Summary
Claims to have proved the great antiquity of several plant races. But this does not contradict the tendency to vary. Insists that heredity can make permanent varieties of sufficient duration to occur as fossils.

From Gaston de Saporta 16 December 1877
Summary
He has heard CD is about to be elected to the Académie des Sciences.
Cross and self-fertilisation, with its emphasis on insect pollination, helps explain the problem he has worked on for so long: i.e., the rapid diversification of angiosperms in the fossil record occurs in conjunction with the diversification of insects.

From Gaston de Saporta 6 September 1868
Summary
Strong support for theory of descent.
Observations on palaeobotany of S. France. Most woody angiosperm genera date far back. Magnolia type unchanged. Intermediate fossil species. Ancient species of Quercus persists as variety of modern species. Fossil evidence of ice age.
CD’s works have been an inspiration in France.
