From Edward Frankland 15 July 1873
Royal College of Chemistry | Kensington Museum
July 15/73.
My dear Sir
I shall deem it a privilege if I can be of any service to you in your very interesting investigations of Drosera. Herewith I forward some pure carbonate of soda (which I prefer to carbonate of ammonia) and if you will wash the glands in about 20 grams of it dissolved in 1 oz. of distilled water, I will do my best to discover what the solvent you mention consists of.1 I fear it will be necessary to wash a very large number of leaflets, say 8 oz. or so, to get a sufficiently concentrated solution.2
I should not think muriatic acid probable, but possibly formic, acetic, oxalic or lactic acid may be present.3 However we must not prejudge the case.
Believe me | Yours sincerely | E. Frankland
