A scarce first edition of The Universal Calculator; or The Merchant's, Tradesman's, Family's and Infant's Tables by John Thomson, published in Edinburgh in 1784.
Designed as a practical working reference, this compact volume contains extensive printed tables for merchants, shopkeepers and tradesmen, enabling rapid calculations of prices, commissions, exchange, weights and measures in the days before mechanical calculators. Works such as this were indispensable business tools throughout the eighteenth century and were intended for everyday commercial use rather than preservation, making surviving first editions increasingly difficult to find.
This example is particularly appealing, retaining its original full leather binding and bearing the author's signature beneath the printed statement "None of these Books are warranted Genuine... but those signed by the Author's own hand, as under." It also contains period ownership inscriptions and numerous contemporary manuscript calculations, providing an authentic glimpse into its original working life.
