Washington, D. C., Oct. 8, 1900.
To the Editor:
—In Surgeon Wasdin's paper, published in The Journal, Oct. 6, 1900, p. 807, he says:During my experimental work we were honored by a visit, at our laboratory in Havana, from Dr. Sternberg, who said to me, while passing through our animal room, that the strongest argument against the acceptance of the specificity of any one of the organisms advanced as the cause of yellow fever, was the fact that no one of them, during experiments in laboratory, had ever communicated this disease by natural infection to the animals of those laboratories; and he asserted that, whenever such infections should occur, the lesions being characteristic, and the organism recovered, he would accept that organism thus demonstrated as the cause of yellow fever, and such demonstration as the proof of its specificity.I think that Dr. Wasdin must have misunderstood me.
