Excerpt from The Advanced Part of a Treatise on the Dynamics of a System of Rigid Bodies: Being Part II of a Treatise on the Whole Subject This volume is intended to be a continuation of that already published as Part I. in 1882. The time occupied in its preparation has been longer that I had anticipated. This is partly due to the want of sufficient leisure, and partly also because as I proceeded with the work new questions to which no sufficient answers had yet been given seemed continually to arise. The pleasure and labour of attempting to answer these, however imperfectly, has delayed the book. Although a large portion of this volume has already appeared in the latter half of the third edition, yet much of this has been recast and new illustrations and explanations have been given wherever they appeared to be necessary. Besides this much new matter has been added. Exactly also as in the last edition those parts to which the student should first turn his attention are printed in a larger type than the rest. Following the same plan as in Vol. I, the several Chapters have been made as independent as possible. The object in view was that the reader should select his own order of study. Historical notices and references have been given throughout the book. But it has not been thought necessary to refer to the author's own additions to the subject, except when they have been first published elsewhere. In this volume much use has been made of the new symbol for a fraction lately introduced by Prof. Stokes.
