"We have not a day to lose if our [Vivisection] Bill or our petition is to do any good". Reports on the activities of the opposition and the attitude of politicians on the subject. Believes a meeting with a minister should be arranged and thinks Lord Derby would be a good man. "All will depend on some half-dozen or 9 or 12 men agreeing on the bill."

Has written to Lord Derby about the vivisection issue and urged him to speak to the proper members of the Cabinet to prevent "hasty legislation versus science". CD offered to send the sketch of the bill that has been drafted or a small deputation to wait on any member of the Cabinet. Lubbock does not think the petition should be presented as he feels sure that nothing will be done this session.

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.

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.

CD has seen Sir John [Lubbock] who suggests that L. Playfair would be the best man to present the [vivisection] petition, but thinks the proposed bill much more important and useful. JL also suggests that the bill be given a more humanitarian aspect and that it be presented to both Houses of Parliament.

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.
