To Gaston de Saporta   12 August 1876

Summary

Thanks GdeS for his Recherches sur les végétaux fossiles [1876].

Author:  Charles Robert Darwin
Addressee:  Louis Charles Joseph Gaston (Gaston) de Saporta, comte de Saporta
Date:  12 Aug 1876
Classmark:  Archives Gaston de Saporta (private collection)
Letter no:  DCP-LETT-10568

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.

Letter no:  DCP-LETT-10591

To Gaston de Saporta   11 October 1877

Summary

Thanks GdeS for communicating his discovery. It is especially important at a time when several naturalists have declared that development occurs quite suddenly at intervals. Joseph Le Conte in N. America urges that even new families and orders are developed within an extremely short period.

Classmark:  DAR 147: 422
Letter no:  DCP-LETT-11179

To Gaston de Saporta   24 December 1877

Summary

Such honours as proposal for election to Institut affect CD very little.

GdeS’s idea that dicotyledonous plants were not developed until sucking insects evolved is a splendid one. The suggestion that fertilisation of the surviving members of the most ancient dicotyledons should be studied is a good one. CD hopes GdeS will keep it in mind.

Classmark:  Archives Gaston de Saporta (private collection)
Letter no:  DCP-LETT-11287

To Gaston de Saporta   31 January 1878

Summary

Has sent GdeS’s drawing to Hooker. He, Oliver, and Thiselton-Dyer have been perplexed by it.

L. Lesquereux’s discoveries in the Cincinnati Lower Silurian beds.

Addressee:  Louis Charles Joseph Gaston (Gaston) de Saporta, comte de Saporta
Date:  31 Jan 1878
Classmark:  Petit and Théodoridès 1959, pp. 210–11
Letter no:  DCP-LETT-11341

To Gaston de Saporta   4 February [1878]

Summary

The Permian fossil sent by GdeS has stirred up the Kew botanists. Hooker suggests it was a Ceratopteris.

Author:  Charles Robert Darwin
Addressee:  Louis Charles Joseph Gaston (Gaston) de Saporta, comte de Saporta
Date:  4 Feb [1878]
Classmark:  Conry 1972, p. 118
Letter no:  DCP-LETT-11347

To Gaston de Saporta   15 August 1878

Summary

It would be false to pretend he cares very much about his election to the Institut.

Glad to hear GdeS plans to publish a work on the more ancient fossil plants. Hopes he will report also on the more recent Tertiary forms because the close gradation of such forms is "a fact of paramount importance for the principle of evolution".

Letter no:  DCP-LETT-11661

To Gaston de Saporta   22 December 1878

Summary

Thanks for GdeS’s Le monde des plantes [1879].

CD has just read "Végétation polaire" [C. R. Congr. Int. Sci. Geogr. 1 (1878): 197–242] with interest. Hooker gave it conspicuous place in his Royal Society Address (1878).

To Gaston de Saporta   19 January 1879

Summary

Thanks GdeS for his photograph; sends his own. Glad to hear GdeS’s work [Le monde des plantes (1879)] is popular in France.

To Gaston de Saporta   13 [May] 1881

Summary

Thanks for work sent by GdeS and A. F. Marion [L’évolution du règne végétal 1 (1881)]. CD greatly pleased at boldness with which GdeS expresses his belief in evolution. Some of GdeS’s countrymen have been "a little timid" on this head.

To Gaston de Saporta   8 April 1872

Summary

Responds to GdeS’s comments on Descent [see 8246]. Cannot give up belief in close relationship of man to higher Simiae.

Author:  Charles Robert Darwin
Addressee:  Louis Charles Joseph Gaston (Gaston) de Saporta, comte de Saporta
Date:  8 Apr 1872
Classmark:  Archives Gaston de Saporta (private collection)
Letter no:  DCP-LETT-8282

To Gaston de Saporta   30 May 1874

Summary

Thanks GdeS for his "Études sur la végétation" [Ann. Sci. Nat. (Bot.) 5th ser. 15 (1872): 277–315]. "Nothing can be more important … than your evidence of the extremely slow and gradual manner in which specific forms change."

Hopes GdeS will shed light on whether polymorphic forms like Rubus and Hieracium are generating new species at present; CD doubts this.
