"Very truly, your friend and brother,

"Clapham, August 25th, 1853.

"My dear Sir:—

"Your determination to spend some time in Great Britain, and to employ yourself, as opportunities occur, in giving lectures and delivering addresses upon American topics, including the social position of the free colored population—for which your education and personal experience eminently fit you—has given me sincere pleasure. I trust you will meet with ample encouragement from the friends of Abolition throughout the United Kingdom, to whose sympathy and kindness I would earnestly recommend you, and still more your heroic and most estimable lady.

"Believe me, most truly yours,

"Professor W. G. Allen"GEORGE THOMPSON."
