INTRODUCTORY TEXT-BOOK OF GEOLOGY.

With Engravings on Wood and Glossarial Index.

Fourth Edition, price 1s. 6d.

"Of late it has not often been our good fortune to examine a text-book on science of which we could express an opinion so entirely favourable as we are enabled to do of Mr Page's little work."-Athenæum.

ADVANCED TEXT-BOOK OF GEOLOGY,

DESCRIPTIVE AND INDUSTRIAL.

With Engravings and Glossary of Scientific Terms.

Second Edition, Revised and Enlarged, price 6s.

"An admirable book on Geology. It is from no invidious desire to underrate other works -it is the simple expression of justice-which causes us to assign to Mr Page's Advanced Text-Book' the very first place among geological works addressed to students, at least among those which have come before us. We have read every word of it with care and with delight, never hesitating as to its meaning, never detecting the omission of anything needful in a popular and succinct exposition of a rich and varied subject. The ordonnance of its material is clear, masterly, and philosophical. The exposition is often eloquent, without ever striving after rhetorical effect. The information is lucidly, yet briefly given. The three passages (quoted) sufficiently indicate the quality of the book; its merits as a text-book can only be estimated by the student himself. If it does not drive many a student, hammer in hand, into quarries and railway cuttings, for immediate experience of geological phenomena, nothing will."-Leader.

"It is therefore with unfeigned pleasure that we record our appreciation of his 'Advanced Text-Book of Geology.' We have carefully read this truly satisfactory book, and do not hesitate to say that it is an excellent compendium of the great facts of Geology, and written in a truthful and philosophic spirit."-Edinburgh Philosophical Journal.

THE GEOLOGICAL EXAMINATOR.

A Progressive Series of Questions adapted to the Introductory and Advanced Text-Books of Geology. Prepared to assist Teachers in framing their Examinations, and Students in testing their own Progress and Efficiency.

HANDBOOK OF GEOLOGICAL TERMS & GEOLOGY.

In Crown Octavo, price 6s.

"Every science, like every manual art, must have its own technicalities and modes of expression new objects require new names, and new facts new phrases to express their relations. There is no avoiding this necessity in any progressive branch of human knowledge; and the only thing that can be done to lessen the difficulty-next to the rigid exclusion of whatever seems superfluous-is to explain these terms in brief and simple language. This I have endeavoured to do, chiefly with a view to the requirements of the general reader, at the same time appending such details as might render the volume an acceptable Handbook of Reference to the student and professed Geologist."-Author's Preface.
