Abstract
A VERY timely book; and useful to instructors in the elements of the subject in providing a number of apt and eloquent illustrations of fundamental ideas. It represents a series of lectures addressed to engineering students, liable to be repelled by pure abstractions, and preferring concrete representations in which their ideas can take root; a complete contrast to the ordinary mathematical text-book of the school of Todhunter. The author should point out that the gradient of 1 in 100 (p. 13) means an angle whose tangent is 0˙01 only in the indoor mode of reckoning on a plane; but that in construction of the railway, the angle is made with a sine of 0˙01; the two modes of measurement are indistinguishable practically.
