Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1859 edition. Excerpt: ... the several lines proceeding from pG will be represented as follows. 1st Dir. GB (as not departing from the standard) = 0. Dir.GE =e. Dir. GA (as the reverse of GB) = 0 +180 = 180. Dir. GH (as the reverse of GE) = e-L.180. 2d Dir. GB (after an entire revolution) = 360. As CD has the same direction with AB, and EF is a straight line, the directions of the lines proceeding from pH will be represented in like manner; thus, 1st Dir. HD = 0, Dir. HG = e, Dir. HC = 180, Dir. HF = eo _(_ isoo, 2d Dir. HD = 360. b.) As the magnitude of an angle depends simply upon the difference between the directions of its sides ( 9. a), the values of the several angles around G and H may now be obtained by subtraction. Thus, EGB (= Dir. GE--1st Dir. GB), or) 0 _ 0 _ 0 GHD (= Dir. HG--1st Dir. HD), e"' AGH (= Dir. GH-Dir. GA), or j, _ CHF (= Dir. HF--Dir. HC), ( 'ttm AGE (= Dir. GA--Dir. GE), or ) _ _ 0 GHC (= Dir. HC--Dir. HG), '. BGH (=2d Dir.GB--Dir. GH), or) =360--('+18(F) DHF (= 2d Dir. HD--Dir. HF), =180--e. It will be observed, that the four angles, EGB, GHD, AGH, and CHF, have the same value, viz. e; and also, that the four, AGE, GHC, BGH, and DHF, have the same value, viz. 180--e, or, in other words, the supplement of e ( 30. g). c.) Substitute fore a particular number, as 60, and the directions of the several lines will be thus represented: 1st Dir. GB or HD = 0, Dir. GE or HG = 60, Dir. GA or HC = 180, Dir. GH or HF = 60 + 180(c) = 240, 2d Dir. GB or HD = 360. The values of the angles will then be as follows: EGB, or GHD, = G0--0, = 60. i Class I. AGH, or CHF, = 240--180, = 60. ) Acute. AGE, or GHC, = 180--60, = 120. ) Class E. BGH, or DHF, = 360--240, = 120. 5 Obtuse. What will be the direction of each line, and the value.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from First Lessons in Geometry: Upon the Model of Colburn's First Lessons in Arithmetic I. It aims to give a simpler and plainer form to the ele ments of Geometry, and thus to bring the science, without sacrificing any of that strictness of demonstration which is its peculiar glory, within the province of the common school, and the reach even of the quite young. The relations of place, and form, and magnitude are those of which the youthful, not to say the mature, mind conceives most easily and most distinctly; and it has long seemed to me a subject for regret, that we have had no work in our list of common school books (however excellent treatises may have been pre pared for higher institutions, or for special purposes) to take advantage of these juvenile conceptions, to give to them a scientific form, and to make them the foundation of elevated and accurate attainment.

Book excerpt: Excerpt from First Lessons in Geometry The child's powers of sensation are developed before his powers of conception, and these before his reasoning powers. This is, therefore, the true order of education and a powerful logi cal drill, like Colburn's admirable first lessons of Arithmetic, is sadly out of place in the hands of a child whose powers of observation and conception have, as yet, received no training whatever. I have, therefore, avoided reasoning, and sirnply given interesting geometrical facts, fitted, I h0pe, to arouse a child to the observation of phenomena, and to the perception of forms as real entities.
