The forms of analysis are thought t - o be of great service bcttl to the teacher and pupil. It is also suggested, that the pupil be thoroughly drilled iu Lr eons 111, and IV, Sect.

It is the object of this book to train and develop the mind by means of the science of numbers. Numbers are the iilstruments here employed to strengthen the memory, to cultivate the faculty of abstraction and to give force and vigor to the reasoning powers. b All our ideas of numbers-are either of unity or of multiplicity-unity being the elementary idea from which all others are derived. A true analysis must conform to the nature of the subject analyzed. It must separate all the ideas and prihcip es into their primary elements, nd then explain and make manifest the laws by which these elements are connected with each other. Hence, the analysis of numbers must begin Gith the - unit 1,-for this is the foundation, and the science is hut the developlnent of the various processes by which 611 other - numbers are derived fro111 1, as a base, and a comparison of the base 1, W-ith-then umbers so derived. Every number has what we call a 6ase that is, number being a collection of things of the same kind, one of these things is . the base of the number mid this thi zu. is called a unit. If we have. the u111-, ber 3 hundred, we may consider it in several points of view l st. It ia one hundred taken 3 times, and if me regard one hundred as the base, then, the base is taken 3 times to make up the number and 100 is the unit. 2nd...
