Happily, the notary was almost a relation,--in this wise: The grandfather of Monsieur Claes had married a Pierquin of Antwerp, of the same family as the Pierquins of Douai. Since the marriage the latter, though strangers to the Claes, claimed them as cousins. Monsieur Pierquin, a young man twenty-six years of age, who had just succeeded to his father’s practice, was the only person who now had access to the House of Claes. Madame Balthazar had lived for several months in such complete solitude that the notary was obliged not only to confirm the rumor of the disasters, but to give her further particulars, which were now well known throughout the town. He told her that it was probably that her husband owed considerable sums of money to the house which furnished him with chemicals. That house, after making inquiries as to the fortune and credit of Monsieur Claes, accepted all his orders and sent the supplies without hesitation, notwithstanding the heavy sums of money which became due. Madame Claes requested Pierquin to obtain the bill for all the chemicals that had been furnished to her husband. Two months later, Messieurs Protez and Chiffreville, manufacturers of chemical products, sent in a schedule of accounts rendered, which amounted to over one hundred thousand francs. Madame Claes and Pierquin studied the document with an ever-increasing surprise. Though some articles, entered in commercial and scientific terms, were unintelligible to them, they were frightened to see entries of precious metals and diamonds of all kinds, though in small quantities. The large sum total of the debt was explained by the multiplicity of the articles, by the precautions needed in transporting some of them, more especially valuable machinery, by the exorbitant price of certain rare chemicals, and finally by the cost of instruments made to order after the designs of Monsieur Claes himself.
