Summary:

Believes Lyon Playfair has been led to compromise too far on bill about animal experimentation as a result of pressure from men wishing to suppress science. A full enquiry is to take place. [See 9987.] Suggests that CD send Playfair Huxley’s letter on the subject.

From:
John Scott Burdon Sanderson, 1st baronet
To:
Charles Robert Darwin
Date:
31 Dec 1880
Source of text:
University of British Columbia Library, Rare Books and Special Collections (Darwin - Burdon Sanderson letters RBSC-ARC-1731-1-42)
Summary:

Signs a certificate sent to him by CD [see 12954].

Sends CD a ticket to his lecture on 25 February, in which he will propose that the mode by which the excitable parts of plants influence other parts at a distance is essentially the same as in the excitable structure of animals, contrary to the views of Hermann Munk and Julius Sachs.

Interested in chapters 6 and 7 of Movement in plants.

From:
Charles Robert Darwin
To:
John Scott Burdon Sanderson, 1st baronet
Date:
29 Mar 1873
Source of text:
DAR 147: 406
Summary:

Reports that he has not received JSBS’s book on histology and physiology [Sanderson ed., Handbook for the physiological laboratory (1873)], which Edward Emmanuel Klein told CD’s son was to be sent. He asks for information so that he may thank Dr Klein. [Klein and Michael Foster were co-authors with JSBS.]

He has returned the Gazette to Dr T. L. Brunton. [See 8825.]

To:
John Scott Burdon Sanderson, 1st baronet
Date:
26 June [1873]
Source of text:
University of British Columbia Library, Rare Books and Special Collections (Darwin - Burdon Sanderson letters RBSC-ARC-1731-1-08)
Summary:

Would welcome JSBS visit to discuss Drosera. Nitrogenous fluids can act as ferments only if they act merely by exciting molecular movement in adjoining molecules.

Glass and cotton excite movement and cause cell contents to change visibly. Huxley coming to see this phenomenon.

Studied effect of poisons 12 or 15 years ago to see whether the action was similar to that on nervous tissue.

DCP-LETT-8987

From:
Charles Robert Darwin
To:
John Scott Burdon Sanderson, 1st baronet
Date:
25 July 1873
Source of text:
University of British Columbia Library, Rare Books and Special Collections (Darwin - Burdon Sanderson letters RBSC-ARC-1731-1-11)
Summary:

Describes his recent work on Drosera digestion of organic materials, e.g., albumen and gelatin. Edward Frankland has given CD a rough test for pepsin. Some plant extracts cause as much inflection as meat. Has found some reversible inflection with heat and perhaps some heat rigor. Has measured the extreme sensitivity of Drosera with very dilute solution of ammonium phosphate.

Source of text:
University of British Columbia Library, Rare Books and Special Collections (Darwin - Burdon Sanderson letters RBSC-ARC-1731-1-13)

John Scott Burdon Sanderson, 1st baronet
Date:
27 Aug 1873
Source of text:
National Library of Scotland (MS.6103 ff.101)
Summary:

CD can provide leaves of Dionaea if JSBS wishes to investigate electric currents in them.

His experiments show that the digestive action of Drosera seems like that of true digestion.

To:
John Scott Burdon Sanderson, 1st baronet
Date:
9 Sept [1873]
Source of text:
University of British Columbia Library, Rare Books and Special Collections (Darwin - Burdon Sanderson letters RBSC-ARC-1731-1-14)
Summary:

Pleased JSBS has decided to work on Drosera; sends plants. Does not know whether thermo-electric pile could detect temperature change when leaves close.

CD’s experiment with very weak hydrochloric acid repeated with success: the plants digest albumen more quickly.

Asks for pure animal substances [proteins] for Drosera experiments. His other sources have been T. L. Brunton, Edward Frankland, W. A. Miller (now dead), and Hoffmann of Berlin [A. W. von Hofmann?].
