Comments on writings of JD on the chemistry of plants [letter completed 1845-5-7].
Critiques JD's paper on plant chemistry, contrasting 'luminous, colorific, calorific, & chemical or photographic' rays. Physics of light. [Letter continues two months later.] JH is done with photography. Has no desire to claim priorities in that field. Entrusts future to JD and others.
