RECOMMENDATIONS.

I have examined, with much care, the proof sheets of "Mensuration of Superficies and Solids," by the Rev. J. M. SCRIBNER, and it gives me pleasure to state that I have been very favorably impressed with the character of the book. I am satisfied that it is well adapted to the wants and capacities of those for whom it is intended; more so than any other production, of a similar kind, with which I am acquainted. WM. HOPKINS,

Principal of the Auburn Academy.

AUBURN, April 19th, 1844.

I fully concur in the foregoing opinion of Mr. Hopkins, and will add, that I hope to see the work introduced as a Text Book in our Schools.

P. H. PERRY,

Town Superintendeut of Com. Schools.

AUBURN, April 20, 1844.

DEAR SIR: Your "Mensuration of Superficies and Solids," is a work, the want of which has long been felt in our Common Schools. Its purely practical character must at once commend it to the favor of the discerning; and our older pupils should not, and I trust will not, rest satisfied short of an acquaintance with the principles which the work so clearly illustrates and applies.

Very Respectfully, Yours &c.

E. G. STORKE,

Rev. J. M. SCRIBNER. County Superintendent of Common Schools.

PREFACE.

MATHEMATICS is studied either as a necessary branch of a finished education, or by those who are anxious to store their minds with scientific facts and principles, to qualify them for active usefulness and the various employments and professions to which they may be called in after life. The scholar by studying a system of theory may have all his ends answered, but the practical mechanic, the engineer, and the man of business cannot follow their professions and perform their part with propriety without being expert in most branches of mathematics.

The work now presented to the public, had its origin in a desire on the part of the author to draw up a practical treatise on the Mensuration of Superficies and Solids for the use of advanced scholars in Schools and Academies. It is conceded on all hands that this important and useful branch of mathematics has been too much neglected, and that the time has come when a work comprised within moderate limits, and adapted to the wants of our young men of ardour and enterprise, who intend devoting them
