THE PROGRESSIVE SCIENCE SERIES 



A BOOK OF WHALES. By F. E. BEDDARD, M.A., 

 F.R.S. With 40 Illustrations by Sidney Berridge. 6s. net. 



A distinct gap in the literature relating to whales has been filled by this 

 book, for it provides in a comparatively small compass a general account of 

 this group of mammals. The aim has been to produce a solid book tempered 

 by anecdote. It is not a monograph of the Cetacea ; but on the other hand, 

 at least, the main facts of structure and mode of life of these interesting and 

 remarkable creatures are given.

VOLCANOES : Their Structure and Significance. By 

 T. G. BONNEY, D.Sc., F.R.S., Emeritus Professor of Geology 

 at University College, London. Third (new and enlarged) 

 Edition. With numerous Illustrations. 6s. net. 



' I have endeavoured to lead the reader through descriptions of the varied 

 phenomena of volcanic action in the present and in the past towards ascertain 

 ing by inference the cause, or causes, of eruptions. For this reason I begin 

 by an account of the " living volcano," choosing instances which may exhibit 

 it (to continue the metaphor) at every stage from birth to death. Next I 

 conduct the reader to the dissecting theatre, and point out what may be dis 

 covered in this method of study. I then recount the geological history of 

 volcanoes in a single country, with a view of bringing out the changes in the 

 position of vents, and in the nature of ejected materials, and, lastly, I describe 

 the distribution of volcanoes either at present or in comparatively recent times, 

 in the hope of finding something suggested by their geographical position and 

 modes of occurrence. In the last chapter I sum up the results to which our 

 investigations have apparently pointed, and endeavour to ascertain the con 

 clusions to which they lead.' Extract from Professor Bounty's Preface.
