WASHINGTON, March 1, 1862.

Honorable WILLIAM H. SEWARD, &c.

SIR: I have received a letter from John C. Brain, who informed me that he has been released from prison and bets me to make inquirries concrning a sum of $220 which he states to have been taken from him when he was arrested.

You may perhaps remember that reference was made to this sum of money in a dispatch from Her Majesty's consul at New York to me dated the 23rd of October which I left with you for perusal on the 26th of that month, and which you were so good as to return to me on thesame day. It was stated in that dispatch that Mr. Brain had informed theconsul that a sum of $220 in gold was taken from him at Camp Colfax, in Indiana, by a private soldier by order of a captain; that no acknowledgment was given to him for the money and that he was very desirous that inquiry should be made concerning its safety.

Brain now informsme that it was Captain Blake, of the Ninth Indiana Regiment, who took charge of the sum in question. He states further that after an imprisonment of nearly six months he is turned out entirely destitute of money and suffering from a severe rheumatic attack brought on by confinement and by sleeping during nine days on a stone floor.

I beg to recommend the matter to your attention and to express a hope that the money may be restored to this poor man without delay.

I have the honor to be, with high consideration, sir, your most obedient, humble servant,

LYONS.
