To J. S. Burdon Sanderson 25 July 1873
Summary
Describes his recent work on Drosera digestion of organic materials, e.g., albumen and gelatin. Edward Frankland has given CD a rough test for pepsin. Some plant extracts cause as much inflection as meat. Has found some reversible inflection with heat and perhaps some heat rigor. Has measured the extreme sensitivity of Drosera with very dilute solution of ammonium phosphate.
