Darwin is sending the plants and suggests any results obtained would be worth publishing by Burdon-Sanderson.; described the nature of the leaf contradictions and the effect of hydrochloric acid on the digestive powers of Drosera. A.L.S. 1 p. Printed in Darwin Frances. More Letters of Charles Darwin, V. 2, p. 394.Transcript: a common thermometer. But if there is any change in temperature, I should expect it would occur some 8 to 12 or 24 hrs after the leaf has been given a big smashed fly, & when it is copiously secreting its acid digestive fluid. I forgot to say that as far as I can make out, the inferior surface of the leaf is always in a state of tension, & that the contraction is confined to the upper surface; so that when this contraction ceases or suddenly fails (as by immersions in boiling water) the leaf opens again, or more widely than is natural to it.- Whenever you have quite finished I will send for the plantsCreator: Darwin, Charles, 1809-1928Date Created: [1873]-09-09Source: Original Format: University of British Columbia Library.
