Dear Sir

I write one line to thank you very much for your second note. I now understand what is to be done, & as soon as my son Francis returns home we will endeavour to make the solution according to your instructions.1

Believe me Dear Sir | yours faithfully & obliged | Charles Darwin

The notes have not been found. Francis Darwin was in Wales (see letter from Francis Darwin, [1 August 1880]); he had been doing experiments that involved chemical analysis, and CD had asked Edward Frankland to recommend a trustworthy analyst to assist with the work (see letter to Edward Frankland, 20 April 1880).
