I SHALL not amuse the reader with any pompous eulogium on the merits of this work; or endeavour, as is customary, to anticipate the public favour by a recital of excellencies, which, in the opinion of some, may be of a disputable nature. This much I may venture to say-the adding one to the number of treatises aiready extant, will not appear superfluous, when we consider the importance of the subject. I'ne design of this work is to furnish schools with a system of practical arithmetic, in which I have, according to my knowledge in this science, arranged the different branches in a judicious and perspicuous order. I shall not here detail the particulars in this book, but refer the reader to the table of contents. I have entirely omitted pounds, shillings, and pence, (except a few examples in exchange with England and Ireland,) as useless to the learner; and have introduced a complete system of Mensuration, (arithmetically,) according to Euclid, and other celebrated authors. This work is in two parts: the second part contains a useful appendix, and a key for Mensuration and the exercise questions. Perfect accuracy, in a work of this size and nature, can hardly be expected: the author and the press are liable to errors. if any such are pointed out, it will be considered as a token of friendship and favour. How far this treatise will answer the end intended, will, in some measure, be obvious to any judicious scholar, by taking a short view of the plan pursued. JAMES L. CONNOLLY, WASHINGTON, G. C. Ohio, } Schoolmaster. |
