![genera], found to verify each other. The London Assays have been made by Robert Bingley, Esq. F.R.S., the King’s Assay Master of the Mint; and those at Paris by Pierre Frederic Bonneville, Essayeur du Commerce, as published in his elaborate work on the Coins of all Nations. Most of the Foreign Coins, assayed at the London Mint, were supplied for this Work from the Bul- lion Office, by order of the Bank Directors, and were selected as proper average specimens by John Humble, Esq., the Head of that Office. An Explication of Coins follows, which it is hoped may prove useful to Bullion Merchants, Travellers, and Collectors of Coins in general. Here all the various impressions are explained ; and the Legends and other Inscriptions rendered into English, from the Latin, Persian, Arabic, Russian, and other languages. This, it is believed, is the first general Translation of the kind ever published, and has therefore the greater claim to indulgence. Tables of the Proportion between the Weights and Measures of all Trading Countries are next given, as deduced from the experiments already mentioned. The erroneous state of the old Tables has been always a source of perplexity to merchants, as might indeed be expected from the uncertain manner in which they have been formed. Their origin cannot be traced: it can only be conjectured that they have been gradually collected through a long course of ages from doubtful authorities in different countries; and there is no account that the)' have ever been corrected or compared on any general or systematic plan. The only attempt of the kind upon record was made by order of the French Government, in 1747, by M. Tillet, at the Paris Mint; but his experiments were confined to a limited number of Money Weights, and there is reason to believe that the standards which he tried were not all duly attested. As to Comnfercial Weights and Measures, they appear to have been left chiefly to the casual reports of mer- chants, who could not be supposed always to possess#the best means of making accurate experiments.
