My dear Dr. Frankland

The two bottles of pure water arrived safely yesterday & I thank you most heartily, for it is a present of untold value to me.2

Yours very sincerely | Ch. Darwin

The year is established by the fact that CD used large amounts of distilled water for his experiments on bloom on leaves (see Correspondence vol. 27, letter to Edward Frankland, 4 January [1879]).
Frankland had previously supplied CD with water that he had prepared himself, commenting that it was ‘difficult if not impossible to buy pure distilled water’ (see Correspondence vol. 21, letter from Edward Frankland, 27 September 1873).
