Thanks THH for his article in the Academy and his defence of CD and G. H. Darwin against Mivart. Still thinks he should write plainly to Mivart.

CD believes Playfair’s bill would not restrict demonstrations under anaesthetic.

Writes about the Vivisection Bill; there is great fear that it may prevent demonstration dissections on insensible animals.

Writes again on the Vivisection Bill, expresses his desire not to ruin the progress of physiology whilst avoiding useless vivisection.

Asks HAH to keep Francis Darwin’s nomination paper [for Linnean Society] for Huxley to sign on return. FD appends personal note.

Thanks for THH’s essay on species [article for an American encyclopedia].

Will probably never again write on large and general subjects; will keep to easier specific ones such as insectivorous and climbing plants.

Astonished and disgusted at Klein’s evidence. No doubt there will be severe and vicious legislation against physiology. Will give evidence before Commission.

Thanks for Elementary biology [1875]. Wishes he had had a course like it.

Is coming to London. Will call on THH.
