Page 313 - OF THE POINT, RAY, AND CIRCLE. By WILLIAM B. SMITH, Ph.D., Professor of Mathematics in the Tulane University of New Orleans, La. Cloth. $1.1O. "To the many of my fellow-teachers in America who have questioned me in regard to the Non-Euclidean Geometry, I would now wish to say publicly that Dr. Smith's conception of that profound advance in pure science is entirely sound. . . . Dr. Smith has given us a book of which our country can be proud. I think it the duty of every teacher of geometry to examine...
Page 23 - To multiply a decimal by 10, 100, 1000, &c., remove the decimal point as many places to the right as there are ciphers in the multiplier ; and if there be not places enough in the number, annex ciphers.
Page 36 - When a decimal number is to be divided by 10, 100, 1000, &c., remove the decimal point as many places to the left as there are ciphers in the divisor, and if there be not figures enough in the number, prefix ciphers.
Page 202 - Four quantities are in proportion when the ratio of the first to the second is equal to the ratio of the third to the fourth.
Page 313 - I cannot see any cogent reason for not introducing the methods of Modern Geometry in text-books intended for first years of a college course. How useful and instructive these methods are, is clearly brought to view in Dr. Smith's admirable treatise. This treatise is in the right direction, and is one step in advancing a doctrine which is destined to reconstruct in great measure the whole edifice of Geometry. I shall make provision for it in the advanced class in this school next term.
Page 318 - Journal of Education. ELEMENTARY TRIGONOMETRY. . 6th edition. (In this edition the chapter on Logarithms has been carefully revised.) I6mo. $1.1O. *' The work contains a very large collection of good (and not too hard) examples. Mr. Lock is to be congratulated, when so many Trigonometries are in the field, on having produced so good a book; for he has not merely availed himself of the labors of his predecessors, but by the treatment of a well-worn subject has invested the study of it with interest.
