MICROSCOPY 



The Construction, Theory, and Use of the Microscope. By 

 EDMUND J. SPITTA, F.R.A.S., F.R.M.S., etc. With 

 numerous Diagrams and Illustrations. Third Edition. 

 Revised and Enlarged. 



" Let us hasten to urge every student of the microscope who 

 wishes to gain a thorough understanding of its principles and 

 possibilities and its defects, and every user of the instrument 

 who desires a work of reference to which he may turn for an 

 explanation of some unexplained optical phenomenon, or for 

 particulars of up-to-date apparatus, to procure a copy of 

 Mr. Spitta's book without delay." Nature. 



THE RECENT 



DEVELOPMENT OF PHYSICAL SCIENCE 



By W. C. D. WHETHAM, M.A., F.R.S., Fellow of Trinity 

 College, Cambridge. With Illustrations. 4th Ed. 6s. net. 



The author has sought to express the results of recent 

 physical investigations in a form which " might prove useful 

 to students of science in general " and " also appeal to those 

 who, with little definite scientific training, are interested in 

 the more important conclusions of scientific thought." The 

 continuous demand for his book, now in its fourth edition, 

 is evidence that he has successfully accomplished his task. 



FORM AND FUNCTION 



A Contribution to the History of Animal Morphology. By 

 E. S. RUSSELL, M.A., B.Sc., F.Z.S. With Illustrations. 



i2s. net. 



This book deals with the principles of comparative anatomy, 

 under the form of an historical account of the development 

 of the science from Aristotle to W. Roux, and it is shown 

 that the history of morphology, hitherto somewhat neglected 

 in this country, throws considerable light upon its present 

 problems. 



" A scholarly and thoughtful book. It is based on many 

 years of first-hand study of the documents and is illumined 

 by insight." Nature.
