Price 6d., FOR THE FIRST AND SECOND BOOKS OF EUCLID. CRITICAL NOTICES. “Mr. Green's 'Gradations' is a valuable work, though it takes in only the first two books of Euclid. Without endorsing all the detail, which we have not had time to examine, we may unhesitatingly speak in praise of the method, which we have examined with care. No introductory Euclid which has fallen in our way contains anything like the help, in the shape of notes and arrangement, that this does.” “ The whole of the propositions are arranged after the manner recommended by Professor De Morgan, in his Treatise on the Study and Difficulties of Mathematics.' To many of the propositions is appended an account of the practical uses to which the proposition may be applied. An Appendix is added, which contains much that is useful in the way of notes and exercises. We feel sure that schoolmasters will largely patrouise Mr. Green's 'Gradations in Euclid,' as a very complete apparatus for teaching the First and Second Books."— Papers for the Schoolmaster, July, 1858, p. 112. “We commend the work to the consideration of Teachers."-Atheneum, July 17, 1858. “By printing the distinct parts of the propositions separately a very great help is gained, and the principles more thoroughly learned.”—The Bookseller, July 24, 1858. “ This is a useful book ; in fact, the best introduction to Euclid with which we are acquainted, and we heartily recommend it to the favourable notice of our readers. Its main object is to combine theory with practice, and so soon as a geometrical truth has been established, to point out its use and application.”—The School and the Teacher, August, 1858. "Mr. Henry Green, A.M., has published the first and second books of Euclid, for pupil. teachers and others. We recommend this as a very useful work introductory to plain geometry, and one which may be put into the hands of either schoolboys or adult mechanics with great advantage.”- Manchester Guardian, Dec. 2, 1858.
