ADVERTISEMENT.

THE additions and alterations which have been made in this fifth edition of Mr. BROWN's Logarithmic Tables, are intended to render the work a useful sequel to the treatises commonly employed in teaching the Elements of Geometry. For this purpose, it has been the object of the Editor to exhibit a succinct view of the construction of the Logarithmic and Trigonometrical Tables; and, by a proper selection of Examples, to illustrate the various practical rules which the speculative truths of Elementary Geometry furnish. To every example given in the work, the answer is annexed.

J. W.
