CLIMATE AND TIME IN THEIR GEOLOGICAL RELATIONS: A THEORY OF SECULAR CHANGES OF THE EARTH’S CLIMATE. By JAMES CROLL, of H. M. Geological Survey of Scotland. With Maps and Illustrations. 12mo. Cloth, $2.50.
“I have studiously avoided introducing anything of a hypothetical character. All the conclusions are based on known facts or admitted physical principles. In short, the aim of the work is to prove that secular changes of climate follow, as a necessary effect, from admitted physical agencies, and that these changes, in as far as the past climatic condition of the globe is concerned, fully meet the demand of the geologist.”—_From the Preface._

PHYSICAL EXPRESSION: Its Modes and Principles. By FRANCIS WARNER, M. D., Assistant Physician, and Lecturer on Botany, to the London Hospital, etc. With 51 Illustrations. 12mo. Cloth, $1.75.
“In the term ‘Physical Expression,’ Dr. Warner included all those changes of form and feature occurring in the body which may be interpreted as evidences of mental action. At first thought it would seem that facial expression is the most important of these outward signs of inner processes; but a little observation will convince one that the posture assumed by the body—the poise of the head and the position of the hands—as well as the many alternations of color and of general nutrition, are just as striking evidences of the course of thought. The subject thus developed by the author becomes quite extensive, and is exceedingly interesting. The work is fully up to the standard maintained in ‘The International Scientific Series.’”—_Science._
