Thanks for the acid digestion experiments, which can be printed as they are. CD trying Drosera on dentine and enamel.
Discusses digestion by insectivorous plants, asks JSBS to try same experiments using pepsin as the digestive agent to see how the results compare with CD’s observations on digestive power of Drosera.
Thanks JSBS for his work. CD concludes the ferment of Drosera must differ from pepsin.
JSBS’s article in Nature ["Venus’s fly-trap", 10 (1874): 105–7, 127–8] could not have been better done.
Has found another plant, Pinguicula, which can catch and digest flies.
Thanks for fibrin. Drosera and Pinguicula dissolve it thoroughly.
Has been testing the digestive powers of Drosera; wants to know whether a group of substances that elicit similar responses are related.
Discusses the powers of digestion of Drosera and why certain substances produce less excitement in the plant than others.
Suggests experiments on artificial digestion.
Has been experimenting with phosphates on Drosera and wonders whether animals digest a particular one.
Asks whether Huxley has approached him regarding the introduction of a vivisection act.
Discusses the experiments with phosphates on Drosera and animals.
Considers the question of preparing a petition on the question of animal experiments, with the aim of promoting rather than hindering science. [Response to 9849.]
Considers the question of recognised lecturers being allowed a licence to perform animal experiments without having to obtain a certificate of fitness.
Sends the Memorial [concerning animal experimentation].
Discusses the handling of the Memorial concerning animal experimentation.
Discusses the best means of presenting the draft bill about animal experimentation. Suggests that CD inform Lord Derby that scientific men concurred with the bill that had been prepared. [See 9923.]
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.
Further discussion about the act regulating animal experimentation; believes the licensing of places to be impracticable.
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.]
Lyon Playfair approves the bill concerning animal experimentation and would be prepared to introduce it should it be necessary. Believes a bill could be passed by Parliament by September.
Informs CD that Lyon Playfair would introduce the bill in the House of Commons, and that Lord Cardwell and Lord Shaftesbury had agreed to support it, the former introducing the bill in the House of Lords.
Further discussion of the introduction of a bill by Lyon Playfair on animal experimentation.
