To Edward Frankland 7 October [1873]1
Down, | Beckenham, Kent.
Oct 7th
My dear Sir
Whenever you write about the acid secreted by Drosera, will you have the great kindness to give me a piece of the most sensitive Litmus paper which can be prepared.—2 I have some bought from a druggist, but know not whether it is very sensitive.—3 I am examining certain hairs on plants, which secrete minute drops of viscid matter & thus catch minute flies, & I want to know whether this is ever acid.—4
My dear Sir | Yours sincerely | Ch. Darwin
