To Edward Frankland 12 April 1874
Summary
Finding that the leaves of Drosera digest all the phosphate of lime out of bones and then remain clasped over the bones for a long time, CD wants to determine whether it is the phosphate of lime or the animal matter in the bones that keeps them clasped. He asks EF to send 2 or 3 grams of pure phosphate of lime for his testing. [See 9411.] Will experiment in the summer using EF’s suggestion that leaves might serve to test weak sewage. Results of Sanderson’s experiments with acids of great use.

To Edward Frankland 31 August 1874
Summary
Utricularia catch freshwater Crustaceans, which cannot be digested and rot in the bladders. CD is interested to identify any substance produced in the putrefaction before it is resolved into gases and salts of ammonia. He has reason to believe that the plant absorbs such products.
