CD’s observations on preference of Drosera for milk and nitrogenous fluids, and the effect of nitrate of ammonia are interesting. Asks whether CD is satisfied that the effect is not due to density of fluid or to a chemical irritant. His own observations suggest such possibilities.
His results with pure gum on Drosera spathulata entirely support CD’s opinion. Other observations on insectivorous plants.
Quotes note by Julius Milde on Drosera rotundifolia from Botanische Zeitung (1852): 540.
