Russel Wallace : Alfred Russell Wallace (sic)
"Thank you very much for sending "The Westminster" with your splendid article on the Vaccination Question. It is, without any exception, the clearest and most forcible exposure of the delusion I have ever read, and I am exceedingly pleased that my paper on the subject was the means of converting you.
"You have done what I thought was almost impossible: made the subject intelligible to any intelligent person, and also by your excellent arrangement, your telling illustrations, your forcible and clear-cut argument, and lastly, your really brilliant style, made it not only easy, but pleasant and even amusing reading." . . .
