CD and Emma enjoyed SH’s visit to Queen Anne Street and would like her to come to Down. When he next comes to London, he hopes to call on Fanny Biddulph.

Discusses GJR’s idea of subjecting plants to brief flashes of light.

Hoped to see GJR in London, but was too tired.

Delighted his book Movement in plants has interested GJR.

Asks if GJR has example of dogs calling on each other to go hunting; there is a case half a mile away.

Has heard that Samuel Butler has abused him in his latest book, but he does not intend to look at it.

Comments on Prehistoric Europe.

Asks JG’s opinion of Daniel Mackintosh’s paper ["Results of a systematic survey of erratic blocks", Q. J. Geol. Soc. Lond. 35 (1879): 425–53].

Comments on loess.

Feels uneasy about streams of stone of Falkland Islands.

Thanks for report [on potato experiments].

Still has subscription money for JT’s experiments. How much does he need?

Perhaps you would like to see a very small “tumour” on a lateral branch of the Silver Fur, caused by an Œstrum, as stated (with references) in my Power of Movement in Plants. These tumours are sometimes almost as big as a child’s head. At what age they emit the upright shoot, I do not know.
