light of general publicity can the fruits of science thrive and ripen; there, 

 the value of i)olitical events for the happiness and welfare of the people is 

 problematic and doubiful; here each new discovery, each newly-found fact 

 not only has an indirect value as a step in the progress of knowledge, but is of 

 direct, positive and material value for the whole of humanity." 



In the introductory j)aper of the ill-fated Belgian journal Isis: revue 

 consacree d Vhistoirc dc la science, the editor, M. George Sarton, says: 



"Science is the great peace maker; it is the cement which unites the 

 most elevated and world-embracing spirits of all nations and races, of all 

 creeds. Every nation profits directly by all the discoveries made by other 

 nations. But, alas I while science is essentially international, scientists are 

 not always so. Too often the generous aspirations with which science tries 

 to imbue them are smothered b\' their jingoistic and nationalistic ten- 

 dencies."' 



The examination of the previous list, and this supplement will show 

 that while the literature of the history of science, both general and specific, 

 is very large, there is at present no brief te.xt-book on the subject in English. 

 This gap will, however, soon be filled by two such works, M. Sarton's recent 

 lectures at the Lowell Institute, and a work that has been long in prepara- 

 tion and will shortly be issued, by Professors William T. Sedgwick and 

 Harry \V. Tyler of the ■Massachusetts Institute of Technology.
