-oBILLERICA AcADEMY, (MAss.) Dec. 10, 1807. .
HAVING examined Mr. Danori's system of Arith. metic, I am pleased with the judgment displayed in his method, and the perspicuity of his explanations, and thinking it as easy and comprehensive a system as any
with which I am acquainted, can cheerfully recommend
it to the patronage of Instructors. * SAMUEL WHITING, Teacher of JMathematics.
* FROM MR. KENNEDY, TEACHER of MATHEMATICŞ.
I BECAME acquainted with DABoil.’s School.: A 3TER’s Assist ANT, in the year 1802, and on examining it attentively, gave it my decided preference to any other system extant, and immediately adopted it for the pup is under my charge; and since that time have used it exclusively in elementary tuition, to the great advantage and improvement of the student, as well as the ease and assistance of the Preceptor. I also deem it equaliy well calculated for the benefit of individuals in private instruction; and think it my duty to give the labour and ingenuity of the author the tribute of my hearty approval
and recommendation. ROGER KENNEDY. New-York, March 20, 1811.

I HAVE run through Mr. DABoll’s School MASTER’s
# * THE design of this work is to furnish the schools of the United States with a methodical and comprehensive system of Practical orithmetic, in which I have endeaYoured, through the whole, to have the rules as concise and familiar, as the nature of the subject will permit. During the long period which I love devoted to the instruction of youth in Arithmetic, I have made use of various systems which have just claims to scientific inert; but the authors appear to have been deficient in an “mportant point—the practical teacher’s experience.-so been too sparing of examples, especially in e first rudiments; in conse juence of which, the young upil is hurried through tie ground rules too fast for his apacity. This objection I have endeavoured to obviate in the following treatise. - : In teaching the first rules, I have found it best to encourage the attention of scholars by a variety of easy and familiar questions, which night serve to strengthen their minds as their studies grow more arduous. The rules are arranged in such order as to introduce the most simple and necessary parts, previous to those which are more abstruse and difficult. - To enter into a detail of the whole work would be tedious; I shall therefore notice only a few particulars, and refer the reader to the contents. - w - Although the Federal Coin is purely decimal, it is so nearly allied to whole numbers, and so absolutely necessary to be understood by every one, that I have introduced it immediately after addition of whole numbers, and also shown how to find the value of goods therein, immediately after sim; le multiplication; which may be of great advantage to many, who perhaps will not have an opportunity of learning fractions. In the arrangement of fractions, I have taken an entire *ew method, the advantages and facility of which will afficiently apologize for its not being according to other 1 * :
