Witness.—­I was pledged not to tell the name; the person signed her name Louisa Truit; the information was got by letter; the reason I did not tell, because I thought she might be murdered; I have not the letters, and can’t tell the contents; the letter that I received required a pledge that I would not tell:  I was directed to send my letter to the post-office without any definite place; the representative of Louisa Truit was a man; I saw him in Market street between Third and Fourth, at Taylor and Paulding’s store, in the course of last week; I was brought into contact with the representative of Louisa by appointment in the letter, to get the information; I never heard him tell his name; he was neither colored nor white; we call them with us mixed blood; (I should take you to be colored, said the witness to Mr. Brown.) I suppose he lives somewhere up there; I saw him at my room the next morning; I did not learn from him who wrote the letter; he did not describe the person of the woman in the letter written to me, only her general appearance; Purnell said he burnt the letter.

Mr. Brown demanded the letter, or the proof of its destruction.

I never wrote myself, but my friend, Mr. Henry did; he said so; I never received a letter; it was written to Robert J. Henry; part of the letter was written to me, but not directed to me; the Louisa Truit, who wrote, stated, that for the information he wanted $100 for one of the fugitives; he was referred to the store of Taylor & Paulding, and Mr. Henry would meet him there; when I got to the store, some of the concern let Mr. Henry know that a man wanted to see him; I heard this at the store; the man was there; he was a mulatto man, middle-aged, and middling tall; he is not here, that I know of; can’t tell when I last saw him.  His name I understood to be Gloucester.

Under the severe cross-examination that the witness had been subjected to under D.P.  Brown, he became very faint, and called for water.  Large drops of sweat stood upon his forehead, and he was obliged to sit down, lest he should fall down.  “Take a seat,” said Mr. Brown tauntingly, “and enjoy yourself, while I proceed with my interrogations.”  But the witness was completely used up, and was allowed to withdraw to another room, where fresh air was more plentiful.  The cause of the poor slave woman was greatly strengthened by this failure.

Another witness, named Zachariah Bowen, for the claimants, swore positively that he knew the prisoner well, that she had been hired to his brother for three years by Dr. Purnell, whose slave she was; also he swore that he knew her parents, who were slaves to the said Doctor P.; that he last saw her in 1827, etc.  On cross-examination he swore thus:  “I last saw her in 1827, she was about sixteen or seventeen; she was about an ordinary size, not the smallest size, nor the largest; she was neither thick nor thin; there was nothing remarkable in her more than is common;
