TitlePaper, 'On the phenomena accompanying stimulation of the gland-cells in the tentacles of Drosera dichotoma' by Walter Gardiner
Date1885
DescriptionGardiner relays observations from a series of experiments, first describing the process of his research: 'Pieces of unstimulated leaves, and of leaves stimulated for periods varying from 5 minutes to 72 hours, were examined fresh, or after treatment with alcohol, picric acid, chromic acid, or osmic acid. The most satisfactory results were obtained from specimens treated for 12 hours with 1 and 2 per cent, chromic acid; such strengths dissolving the tannin precipitate first formed, and fixing the structures most successfully. The leaves were fed principally upon small flies or pieces of frog muscle, since these were found to succeed best. Heat stimuli, electrical stimuli, and stimulus produced by contact or cutting were also employed.'
