To Gaston de Saporta 10 September 1876
Summary
Hopes GdeS will publish on subjects discussed in his letter [10587]. CD had noted similar persistence of variation in fossil shells.
Calls his attention to Nägeli’s work on Hieracium.
Expresses skepticism about O. Heer’s view that dicotyledonous plants developed suddenly. Believes they must have developed slowly in some part of the globe completely isolated from other regions.

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.
