| London 23 Nov. 1868.

My dear Sir,

You may use my letter in whatever form you like.

The title of my work is:

“Das Kapital. Kritik der Politischen Oekonomie. First Volume Erster Band . Hamburg 1867.”
“Capital. Criticism of Political Economy. First Volume. Hamburg 1867.”

The  Isidor Gerstenberg: Suggestions for Forming a Council of Foreign Bondholders (London 1868). Siehe Marx an C. D. Collet, 19.11.1868.
Schließen pamphlet I sent you, belongs to Mr. Borkheim. So, after perusal, please to return it. The secret of that pamphlet seems to be: Gerstenberg, agent of the Barings; the Barings, Foreign Loan Contractors, and, especially, loan contractors for the Russian Government.

Yours sincerely
K. Marx

C. D. Collet, Esq.
