Book Description
Excerpt from Barlow's Tables of Squares, Cubes, Square Roots, Cube Roots, Reciprocals, of All Integer Numbers Up to 10, 000 Tms reprint of Mr. Barlow's Tables, as well as that of Lalande which pre ceded it, was suggested by me to the Society for the Diffusion of Useful Knowledge on two grounds. The intrinsic merit of both works made me desirous of seeing them printed in a better type than any in which they had ever appeared; added to which, the latter could only be procured from abroad, and the former was wholly out of print. In the second place, I had long been satisfied, that the old numeral symbols, in which most of the figures had heads or tails, were many times more legible than those of uniform height, introduced, I believe, by Dr. Hutton. From the time when the reprint of Lalande appeared (about twelve months ago) I have heard no one contest this position; and the present work will shew that it is as true of a heavy page (as the printers call it)as of one in which there are fewer figures. At the same time, I cannot claim any credit whatever for the accuracy with which either work has been examined and corrected, except that of knowing where to find those who could do both much better than myself. Mr. Farley, of the Nautical Almanac Office, is answerable for the work on these points: and I feel very sure, that the large number of computers to whom it will prove useful will admit his skill and accuracy; though it must take years of trial and use of the tables to establish their freedom from error. Mr. Barlow's Tables, containing those now published and many others, appeared in 1814; and, considering that they were not stereotyped, do great credit to the printer, (t. Davison, Lombard Street, Whitefriars). The obligations of Mathematicians to the author, for the extent and accuracy, both unprecedented, of his work, have been frequently expressed. This republication (respecting the separate copyright of which an arrange ment has been made by the publishers with Mr. Barlow) omits the tables which are of use only to the mathematician, and contains those which are wanted by the arithmetician and computer. They will be found useful to the more scientific class of engineers and surveyors for immediately obtaining results which are now usually got by logarithmic calculation or the sliding rule; to actuaries (in the table of reciprocals); to school masters, for obtaining examples of the ordinary rules of arithmetic to all, in fact, who are calculators by choice or necessity, though, of course, to some more than to others.
