Letter to The Editor of The Eastern Post, January 20, 1872

Sir, — In The National Reformer of January 7th, Mr. Charles Bradlaugh says:

"We only meant to allege that Dr. Marx had, in former times, given information to his own Government."

I simply declare that this is a calumny, as ridiculous as it is infamous. I call upon Mr. Bradlaugh to publish any fact that could afford him even the slightest pretext for his statement. For his personal tranquility I add that he shall not he "challenged."

I am, Sir, yours obediently,

Karl Marx

January 16th
