Mrs. Lucretia Mott, Mrs. McKim, Miss Sarah Pugh and Mrs. Plumly, volunteered to accompany this poor slave mother to the court-house and to occupy seats by her side, while she should face her master, and boldly, on oath, contradict all his hard swearing.  A better subject for the occasion than Jane, could not have been desired.  She entered the court room veiled, and of course was not known by the crowd, as pains had been taken to keep the public in ignorance of the fact, that she was to be brought on to bear witness.  So that, at the conclusion of the second witness on the part of the defense, “Jane Johnson” was called for, in a shrill voice.  Deliberately, Jane arose and answered, in a lady-like manner to her name, and was then the observed of all observers.  Never before had such a scene been witnessed in Philadelphia.  It was indescribable.  Substantially, her testimony on this occasion, was in keeping with the subjoined affidavit, which was as follows—­

    “State of New York, City and County of New York.
