‎Scarce first edition of this popular work, containing extensive conversion tables including those for interest, for commissions and exchange, primarily for converting to British money.The work was intended to be a support for merchants, traders and bankers for whom it was necessary to quickly be able to look up interest- and exchange-rates. Similar works had been published previously, but this was the most extensive work published at the time. It was reprinted several times. ‎
