To Ernst Haeckel   15 July 1879

Down, | Beckenham, Kent. | (Railway Station | Orpington. S.E.R.)

July 15. 1879

My dear Häckel

On August 1st we all go for a month to the Lakes in Cumberland, as I want a little rest. If your return home is delayed till September & you can possibly spare the time, I hope that you will pay us a visit, as it would be a great pleasure to me to see you.1

I am astonished to hear what a gigantic undertaking the description of the Radiolarians collected during the Challenger expedition proves to be.2

I am glad to hear that your labours on the Medusæ are drawing to a close.3

For Heaven sake do not overwork your brain, & always remember what a tender organ it is.

My dear Häckel | Yours very sincerely | Charles Darwin

Footnotes

The Darwins stayed at Coniston in the Lake District from 2 to 27 August 1879, spending the night of 1 August in London (Emma Darwin’s diary (DAR 242)). Haeckel was planning a visit to Edinburgh at the end of August, possibly returning via London (see letter from Ernst Haeckel, 12 July 1879).
Haeckel was going to describe the Radiolaria collected on the HMS Challenger expedition (see letter from Ernst Haeckel, 12 July 1879 and n. 5).
Haeckel’s Das System der Medusen (the first volume of Haeckel 1879–81) was published in 1879 (see letter from Ernst Haeckel, 12 July 1879 and nn. 3 and 4).
