To Edward Frankland   12 April 1874

This letter is not yet available online.

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.
