Mr. Alfred R. Wallace (Dorking) writes:--"Allow me to correct an error which has occurred in my letter on the 'Drink Traffic' in your paper of Thursday. I refer to 'Mr. Prettyman's [[actually, 'Pretyman' --Ed.]] book on Dispauperization,' for evidence of the effect of the number of public-houses on drunkenness and crime. It should have been, 'Mr. Peek's recent article in the Contemporary Review.' I had just read both, but had neither at hand to refer to, whence the error."
