~THE MEAN DENSITY OF THE EARTH:~ An Essay to which the Adams Prize was adjudged in 1893 in the University of Cambridge. By J.H. POYNTING, Sc.D., F.R.S., Late Fellow of Trinity College, Cambridge; Professor of Physics, Birmingham University. In Large 8vo, with Bibliography, Illustrations in the Text, and Seven Lithographed Plates. 12s. 6d.

"An account of this subject cannot fail to be of GREAT and GENERAL INTEREST to the scientific mind. Especially is this the case when the account is given by one who has contributed so considerably as has Prof. Poynting to our present state of knowledge with respect to a very difficult subject.... Remarkably has Newton's estimate been verified by Prof. Poynting."--_Athenæum._

_Demy 8vo, Handsome cloth, 18s._

Physical Geology and Palæontology,

_ON THE BASIS OF PHILLIPS._

BY

HARRY GOVIER SEELEY, F.R.S., PROFESSOR OF GEOGRAPHY IN KING'S COLLEGE, LONDON.

With Frontispiece in Chromo-Lithography, and Illustrations.

"It is impossible to praise too highly the research which PROFESSOR SEELEY'S 'PHYSICAL GEOLOGY' evidences. IT IS FAR MORE THAN A TEXT-BOOK--it is a DIRECTORY to the Student in prosecuting his researches."--_Presidential Address to the Geological Society, 1885, by Rev. Prof. Bonney, D.Sc., LL.D., F.R.S._

"PROFESSOR SEELEY maintains in his 'PHYSICAL GEOLOGY' the high reputation he already deservedly bears as a Teacher."--_Dr. Henry Woodward, F.R.S., in the "Geological Magazine."_

"PROFESSOR SEELEY'S work includes one of the most satisfactory Treatises on Lithology in the English language."--_American Journal of Engineering._

With Map, Numerous Tables, and Thirty-six Plates.

"No such compendium of geological knowledge has ever been brought together before."--_Westminster Review._

"If PROF. SEELEY'S volume was remarkable for its originality and the breadth of its views, Mr. ETHERIDGE fully justifies the assertion made in his preface that his book differs in construction and detail from any known manual.... Must take HIGH RANK AMONG WORKS OF REFERENCE."--_Athenæum._
