Accented Five-figure Logarithms of Numbers from 1 to 99999 without Differences

Abstract

IN this work are comprised two sets of tables. The first set (pp. 1-221) is indicated by the above title-page; the second is entitled “Accented Five-figure Logarithms of Sines, Tangents, Cotangents, and Cosines of Angles from 0° to 90° to every Hundredth of a Degree” (pp. 224-270). There is, further, a one-page “Comparison of French and English Decimal Scientific Systems at 32° and 39° Fahrenheit in vacuo.” The possessors of the same author's “Accented Four-figure Logarithms” are already acquainted with his principles of accentuation; to those who have not this work we need only say that excess and defect are clearly indicated in the printing, and that the degree of accuracy attainable in any piece of calculation is very rarely inferior to that reached by the longer calculations with the ordinary seven-figure tables. The logarithm of any number is seen at a glance, so that there is no using of differences, proportional parts, or anti-logarithms. In his introduction the author works out some examples with ordinary unaccented five and seven-figure tables, and with these accented tables. On the hypothesis that the tables are correctly printed—we have detected no error—we commend this book as being one that will save much time in calculation without entailing a loss of accuracy. The figures are very clearly printed.
