She began now to engage him in serious discourse; and finding by his replies, that he wanted money to make more powder, she enquired how much would make a stock that would maintain itself? He replied, one fifty pounds after nine months would produce a million. She then begged the ingot of him, which he protested had been transmuted from lead, and flushed with the hopes of success, hurried to town to examine whether the ingot was true gold, which proved fine beyond the standard. The lady now fully convinced of the truth of the empyric’s declaration, took fifty pounds out of the hands of a Banker, and entrusted him with it.
The only difficulty which remained, was, how to carry on the work without suspicion, it being strictly prohibited at that time.

This unlucky accident was 300 l. loss to Mrs. Thomas: yet still the grand project was in a fair way of succeeding in the other wing of the building. But one misfortune is often followed by another. The next Sunday evening, while she was reading to, and instructing her little family, a sudden, and a violent report, like a discharge of cannon was heard; the house being timber, rocked like a cradle, and the family were all thrown from their chairs on the ground.
