Summary

Note on the chemical composition of teeth.

Summary

Encloses a copy of Lord Derby's note of 17 April 1875 (DCP-LETT-9938).

Sir John Lubbock has agreed to meet CD, but no arrangement has been made.

Maybe they should drop the petition, since Lord Derby has agreed to help.

Summary

Encloses letter from Thomas Henry Huxley (DCP-LETT-9942); CD thinks copies of their bill should be sent to Lyon Playfair and Edward Cardwell.

Richard Buckley Litchfield reports the intentions of the Humanitarians.

Summary

Richard Buckley Litchfield will soon be able to send CD revised copies of the bill.

Will write to Sir John Lubbock to ask if he will present the bill.

Summary

Encloses the bill with its corrected preamble. How many copies would he like?

Hopes JSBS can attend the meeting of the Royal Society for the Prevention of Cruelty to Animals on 5 May 1875.

Summary

CD astonished at receiving the Baly Medal of the Royal College of Physicians.

Summary

Has received CD’s letter [see 12050]. Gives CD the history of the Baly Medal and names previous recipients. It is not necessary for CD to be present for the award, but if he chooses to attend, arrangements could be made for him to arrive just before the presentation. CD will not be required to make an acceptance speech.

Summary

Thanks CD for a copy of Erasmus Darwin.

Summary

Requests JSBS sign certificate for [Francis Darwin’s] candidacy [for Royal Society].

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.

Summary

Hears from Frank [Darwin] that Drosera behaves perversely. Suggests that motor influence may move longitudinally away from the excited glands.

Summary

Suggests an explanation for difference in excitability of Drosera leaves to meat and albumen on the one hand and, on the other, fibrin, areolar tissue, gelatin, and fibrous basis of bone.

Summary

Will prepare experiments with the fatty acids on digestion of gluten. Has found it is digested slowly, but entirely, with pepsin and hydrochloric acid.

Summary

Thanks for MS which he intends to read while on a week’s holiday.

Sends thanks for Francis Darwin’s offer of help and says that Francis’s experiments on digestion are complete.

Summary

Sends the Memorial [concerning animal experimentation].

Summary

Informs CD that he has taken no further action about the petition concerning animal experimentation on the understanding that it would be presented only if the government introduced an objectionable bill. [See 9948.]

Summary

Thanks JSBS for his work. CD concludes the ferment of Drosera must differ from pepsin.

Summary

Agrees that CD should write to Lord Derby to say that a bill on animal experimentation was being prepared and that the government should not comment at this stage. [See 9933.] Ridicules the idea of using inspectors. Distinguishes between dissection and vivisection.

Summary

Sends his MS on Dionaea and hopes it may be useful for JSBS’s lecture ["On the mechanism of the leaf of Dionaea muscipula", Not. Proc. R. Inst. G. B. 7 (1874): 332–5].
