It is now thirteen years and a half since the last or ninth edition of the ‘Principles of Geology’ appeared; a long interVal in the history of the progress of a science, in which so many able investigators and thinkers, in every civilised country of the world, are actively engaged. In re-editing the work, I have found it necessary entirely to re-write some chapters and to recast others, and to modify or omit some Passages given in former editions. For the sake of those readers who are already familiar with the ‘Principles,' I subjoin a list of the chief additions now made for the first time,
Pointing out the pages at which corresponding matter occurs in the ninth and tenth editions.

fluenced by astronomical changes; such as variations in the excentricity of the earth's orbit, changes in the obliquity of the ecliptic, and different phases of the precession of the equinoxes, Mr. Croll's suggestion as to the probable effects of a large excentricity in producing glacial epochs is fully discussed, and the question is entertained whether eological dates may be .. by reference to the comined effect of astronomical and geographical causes. 204 335 | The earth-pillars or pyramids of Botzen in the Tyrol and other localities, illustrated by a drawing of Sir John Herschel's, are here introduced, as showing the power of rain as distinct from that of running water. The glacial origin of the formation of which the pillars are made is also pointed out. 223 372 | Notice of the theory of regelation of Tyndal and Faraday in explanation of the motion of glaciers. 376 The glacier-lake of the Alps called ‘the Märjelen See,” described and illustrated by two diagrams, and its bearing on the origin of the parallel roads of Glenroy explained. 393 || Live fish rising in the Artesian wells of the Sahara. 237 398 || Facts relating to the origin of mineral and thermal waters and the hot springs of Bath. 420 Playfair on the origin of the lake-basin of Geneva. 434 Mr. Horner on the mode of computing the antiquity of the Nile mud; with the opinions of Mr. S.

Lubbock, and Mr. Wallace on the subject. 447 A new hypothesis proposed to explain the origin of the ‘mud-lumps of the mouths of the Mississippi, illustrated by a map and two views. - * 271 457 | The antiquity of the delta and alluvial plain of the Mississippi discussed with reference to new facts brought to light during the survey of Messrs.
