Thinks Frank and he have worked out Pinguicula well and they long to attack Utricularia. Tried several plants with sticky glandular hairs; some few absorb ammonia, but the greater number do not. If Hooker sends plant or seed of Lychnis Darwin will examine it to see whether it catches many flies. Asa Gray has written him much about Sarracenia, with a specimen showing the splendid dodge by which ground insects are enticed up and then drowned. Describes how it may be investigated, to see whether it absorbs decayed matter from flies, or ammonia thus generated.
