Sir, In one of your leading articles of to-day you quote a string of phrases, such as, London, Liverpool, and Manchester in revolt against odious capital, etc., with the authorship of which you are kind enough to credit me. Permit me to state that the whole of the quotationsb upon which you base your article are forgeries from beginning to end. You have probably been misled by some of the fabrications which the Paris police are in the habit of issuing almost daily in my name, in order to procure evidence against the captive Internationals at Versailles. I am, Sir, yours, etc., 1, Modena-villas, Maitland Park, Haverstock-hill, N.W., July 11, 1871
