Abstract
A BRIEF examination of this treatise is sufficient to allow us to form a favourable opinion of its contents. Nearly every proposition or description shows that the author is a thorough master of his subject, and, what is also of equal importance, can impart his knowledge to his readers in language both concise and fresh. The treatise is intended for those preparing for the first part of the Mathematical Tripos, and is different from other elementary works on the same subject in the following manner: In this Tripos examination one is now allowed to use the notation of the calculus, which for some students is a great boon, in that problems can be more easily solved, and in less time. We are thus presented in the text of this treatise not only with the usual proofs, but with alternative proofs when the use of the calculus is a distinct advantage. This alteration will be found an improvement. The definition of a fluid, from which are deduced the principles of the subject, is given as “a substance which will yield to any continued shearing stress, however small, or,” in other words, “when a fluid is in equilibrium, the stress across any plane in it is entirely normal to that plane.”
