Sir, - Dr de Courcy Ireland (January 18th) implies that the lack of dissent which his jaundiced views on the United States have elicited in your letters columns constitutes a form of confirmation of their correctness. Someone ought to tell him that nem. con. (nemine contradicente) does not justify a conclusion of QED (quod erat demonstrandum). - Yours, etc., Jack Lewis,
