Observations of effect of pepsin and hydrochloric acid on urea indicate that it is not digested [by Drosera].

Forwards a letter reporting on a blow-fly trapped by a leaf of Dionaea; decomposition of fly has also decomposed the leaf. JDH has written asking for a strong plant, and explaining the case [of surfeit].
