An account of some modern methods of 



Astrophysical Research 



ELIvERY HALE 



The introduction of photographic methods, the improvement of telescopes, and the rapidly 

 increasing appreciation of the value to astronomy of physical instruments and processes, have 

 revolutionized the observatory. From a simple observing station it has been transformed into a 

 great physical laboratory, where images of the Sun and stars are studied with many powerful 

 instruments, and celestial phenomena are experimentally imitated with the aid of electric furnaces 

 and other sources of intense heat. The result has been a great gain in our knowledge of the origin, 

 development, and decay of stars. This book explains in a popular way how the life histories of the 

 Sun and stars are investigated. One hundred and four half-tone plates, made from the best astro- 

 nomical negatives, place before the reader the most recent results of celestial photography in most 

 of its phases. 2jo pages, 104 plates, 8vo, cloth; net $4,00, postage extra,

By Arthur F. Bentley 



This book is a technical study of the methods 

 which must be used in the scientific interpreta- 

 tion of the phenomena of government. Ine 

 author holds that the manner in which ideas and 

 beliefs are made to do service in most present 

 interpretations is artificial and unsatistactory. 

 He has endeavored to resolve the customaiy 

 dualism, not in the manner commonly callea 

 philosophical, but by a direct analysis of social 

 processes. His position is that the concrete use 

 of feelings and ideas as causes should be ab^- 

 doned. and replaced with something more em- 

 cient for scientific purposes. He seeks to tina 

 values or practical meanings for al! social theo- 

 ries and discussions in terms of underlying 

 group interests of the population. While some 

 of these interests may be easily located, "1^^^ 

 he believes, can be detected only by protractea 

 investigation. This is but one side of this worK. 

 On the other side he strives to make a similar 

 analysis of the various institutions or organization 

 forms of government, reducing them likewise 

 to terms of underlying group interests, ana 

 showing how they are created and maintainea 

 by the pressures exerted by such interests. 



The book may perhaps best be described as 

 an attempt to attain a non-dualistic explanauon 

 of the interactions of public opinion in its many 

 forms with the institutions of government, n 

 may safely be said that no such detailed attempx 

 to grapple with the intricacies of public opinion 

 on a strictly social basis has hitherto been made.
