A TREATISE FELLOW AND LATE LECTURER OF ST JOHN'S COLLEGE, CAMBRIDGE. FIFTH EDITION REVISED. Αριστον μὲν ὕδωρ. CAMBRIDGE: DEIGHTON, BELL, AND CO. LONDON: G. BELL AND SONS. 1891 PREFACE. HE present Treatise is a reproduction of the first part THE of a Treatise on Hydrostatics and Hydrokinetics, the third edition of which was published in 1877. The pressure of other work has hitherto prevented me from carrying out the intention, mentioned in the preface to the fourth edition, of reproducing the second part of the treatise, but I still retain the hope, if time and health permit, of doing so at no distant date. The instalment of Hydromechanics, which I now offer to the student, is intended to cover the ground ranged over, in the second four days, in Part I of the Examination for the Mathematical Tripos, and to serve as a stepping-stone in the advance to the higher regions of Hydrokinetics, and its applications to the theory of sound, and the oscillations of liquid waves. The various additions which have been made to several of the Chapters, and the fresh examples, taken from recent examination papers, which have been inserted, will, I hope, increase the usefulness of this treatise in helping the student 406156 to acquire sound views of the theory of the subject, and skill in the solution of examples and problems. I am much indebted to Mr J. Brill, late Fellow of St John's College, for the valuable assistance which he has kindly rendered to me in the revision of Manuscripts and proof sheets and for many important corrections and suggestions.
