S. B. WOOLHOUSE, F. R. A.S.; F.S.S., &c. LONDON: JOHN WEALE, 59, HIGH HOLBORN. 1856. PREFACE. THE measures, weights, and moneys, established throughout the world, are so diversified in their comparative values and systematic relations that a correct classification of them is a task of greater magnitude than would commonly be supposed. In the present work no labour has been spared to ascertain, in every case, the best attainable information, and the various details have been arranged with especial regard to facility of reference. With this object, the materials appertaining to each locality are uniformly tabulated in the same order, and opposite to each separate quantity or value the English equivalent is distinctly exhibited so as to obviate as much as possible the necessity of any calculation. The comprehensive principles which influence the fluctuations of exchange are also briefly stated, and correct rules are given for computing the sterling value of coins and bullion. The tables for the conversion of the standard linear and square measures of one country into those of another were before published in another form, and had recently become out of print. They are here enlarged and more conveniently arranged, and their utility will be fully appreciated by those who may have occasion to consult the architectural and other works of the continent. The second part of the volume relates to the measurement of time, and comprises a detailed investigation of the Christian, Hebrew, and Mahometan Calendars, with formulæ, tables, and practical rules for performing the various calculations. We have been induced to go more at length into these subjects as they are imperfectly treated in chronological works generally. We trust that the typographical accuracy of the volume may be effectually secured by the stereotype plates, and that our earnest endeavour to make it generally useful may in some degree be accomplished. |
