From Daniel Oliver 19 September 1860
Summary
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.
