PREFACE to THE SECOND EDITION.

In preparing this Edition for the press the utmost care has been taken to ensure accuracy to as great a degree as possible. With this view, all the examples contained in the first Edition, and now reprinted, have been again worked out.

The additional matter, which amounts to about one-third of the whole work, consists (1) of Theory of Equations, Hydrostatics and Hydrodynamics ; (2) of Summation and Interpolation of Series, Interest and Annuities, Chances, &c. in Algebra ; of Rotation of Bodies, &c. in Dynamics ; (3) of Problems in Mechanics involving the Differential and Integral Calculus ; (4) of a large increase of examples in all of the subjects, except Geometrical Deductions, that occur in the first Edition, especially in Arithmetic, Algebra, Trigonometry and Mechanics ; (5) of answers to Conic Sections, Exs. 20 -- 46, 170 -- 199.

All the Examples and Problems, in which Logarithms may conveniently be used, have been solved with the aid of tables, in which the logarithms consist of six figures. The Logarithmic Tables, used throughout this work, were edited by the Rev. J. Cape, M.A., &c., Professor of Mathematics in the Honourable East India Company's Military Seminary, Addiscombe.

As in many calculations, logarithms are used rather for convenience than from necessity, the answers obtained will slightly vary, (1) according as logarithms are used or not, (2) according as the tabulated logarithm consists of five, six or seven figures, more or less, and (3) according to the extent of the use made of 'proportional parts.' This variation is generally very small, and an indication of the cause of it will be sufficient to explain the disparity between the answers to some questions obtained on different occasions or by different persons.

Great assistance has been derived from Barlow's Tables of Squares, Cubes, Square Roots, &c., edited by Professor De Morgan, 1840.

In preparing for the first Edition of this Work, the Rev. W. H. Johnstone, M.A. was associated with the author. Other engagements have prevented Mr. Johnstone from contributing his able assistance towards the present volume ; for which accordingly, with all its imperfections, the author is solely responsible.

November 9, 1847.
