"Ah! here it is," she exclaimed triumphantly, producing an obese Morocco purse. "I put it in here for safety, knowing how liable one is to get one's pocket picked in these crowded London streets." She opened the bulky receptacle and drew it out after the manner of a concertina, exhibiting multitudinous partitions, all stuffed with pieces of paper, coils of tape and sewing silk, buttons, samples of dress materials and miscellaneous rubbish, mingled indiscriminately with gold, silver, and copper coins.
