vi PREFACE. The mathematical reader will perhaps be surprised by the rough and ready mode of treatment adopted in some instances. But when it is recollected that, for the most part, we can assign only very hypothetical values for our symbols, it would be affectation to seek close results, which would after all have no greater value than those which claim to be only distant approximations. The course of the argument and the general conclusions, will be found repeated in the Summary at Chapter XXII. But it is hoped that a perusal of this may not be substituted for reading the book. It is believed that the reasoning of the several chapters will be found intelligible, even without wading . through the calculations, My thanks are due to the Councils of the Geological Society of London, and of the Philosophical Society of Cambridge, for permission to make free use of papers contributed by me to their publications. I have similar acknowledgments to make to the Proprietors of the Philosophical Magazine, the Geological Magazine, and the Quarterly Journal of Science. My kind friends, H. W. Bristow, Esq., F.R.S., Senior Director of the Géological Survey, and A. F, GRIFFITH, Esq., B.A., of Lincoln’s Inn, Scholar of Christ’s College, Cambridge, have rendered me most valuable help in revising the proofs while they were passing through the press. OSMOND FISHER.
