From Edward Frankland 27 September 1873
14 Lancaster Gate | Hyde Park W.
Sep. 27/73
My dear Sir
I have sent you per rail a Winchester quart of pure distilled water.1 It is difficult if not impossible to buy pure distilled water.
This has been subjected to the following operations
1. Freed from Ammonia
2. Distilled.
3. Boiled for 6 hours with Permangana⟨t⟩e of Potash2 to destroy organic matter
4. Distilled again.
When it is finished pray let me know & you shall have some more.
When I say it is pure you will of course still understand this in a relative sense. It still contains atmospheric gases in solution and a few zymotic germs in suspension.
Yours sincerely | E. Frankland
Charles Darwin Esq. F.R.S.
