Abstract
WHETHER Mr. Cooke has sufficiently appreciated the labours of De Bary and Oersted, in his article published in your columns of last week under the above title, I leave for others to determine. I wish now merely to call attention to one sentence in his article, as follows:ββIt is manifest that no amount of care in cultivation, under bell glasses or other exclusion from foreign influences, is sufficient against a contingency which dates back to the seed of the nurse-plant.β Does Mr. Cooke mean that the spores of the fungi themselves deposited in the seed of the nurse-plant are carried up, so to speak, in the process of growth, into the leaves, where they germinate; or that the liability to produce parasitic fungi is communicated from the seed to the mature plant by some process which combines the Pangenesis of Darwin with the spontaneous generation of Bastian? I see no other explanation of the sentence than one or other of these alternatives.
