For details, see Griffin's Introductory Science Series, p. 85.


Crown 8vo. Handsome Cloth, 2s. 6d.

RESEARCHES ON THE PAST AND PRESENT HISTORY OF THE EARTH'S ATMOSPHERE.

Including the latest Discoveries and their Practical Applications.

By DR. THOMAS LAMB PHIPSON.

PART I.—The Earth's Atmosphere in Remote Geological Periods.

PART II.—The Atmosphere of Our Present Period. Appendices; Index.

*** Dr. Phipson's work presents, amidst much which is of interest to the Scientist and the General Reader alike, a short résumé of his discovery of the origin of Atmospheric Oxygen, the existence of which he attributes wholly to the action of Solar Radiation upon vegetable life. The book will be found replete with much that is new, curious, and interesting, both in connection with Weather Lore, and with Scientific Meteorology.—Publisher's Note.

"The book should prove of interest to general readers, as well as to meteorologists and other students of science."—Nature.

By PROFESSOR GRENVILLE COLE, M.R.I.A., F.G.S.

Fourth Edition, Thoroughly Revised. With Frontispiece and Illustrations. Cloth, 10s. 6d.

GENERAL CONTENTS.—
PART I.—Sampling of the Earth's Crust.
PART II.—Examination of Minerals.
PART III.—Examination of Rocks.
PART IV.—Examination of Fossils.

"Prof. Cole treats of the examination of minerals and rocks in a way that has never been attempted before ... deserving of the highest praise. Here indeed are 'Aids' innumerable and invaluable. All the directions are given, with the utmost clearness and precision."—Athenæum.

"That the work deserves its title, that it is full of 'Aids,' and in the highest degree 'practical,' will be the verdict of all who use it."—Nature.

"This excellent Manual ... will be a very great help.... The Section on the Examination of Fossils is probably the best of its kind yet published.... Full of well-digested information from the newest sources and from personal research."—Annals of Nat. History.
