recognized. Consequently among the first hundred Monographs appeared 

 works in the form of treatises covering in some instances rather broad 

 areas. Because such necessary works do not now want for publishers, it is 

 considered advisable to hew more strictly to the line of the Monograph 

 character, which means more complete and critical treatment of relatively 

 restricted areas, and, where a broader field needs coverage, to subdivide 

 it into logical sub-areas. The prodigious expansion of new knowledge 

 makes such a change desirable. 



These Monographs are intended to serve two principal purposes: first, 

 to make available to chemists a thorough treatment of a selected area in 

 form usable by persons working in more or less unrelated fields to the end 

 that they may correlate their own work with a larger area of physical 

 science discipline; second, to stimulate further research in the specific 

 field treated. To implement this purpose the authors of Monographs are 

 expected to give extended references to the literature. Where the literature 

 is of such volume that a complete bibliography is impracticable, the 

 authors are expected to append a list of references critically selected on 

 the basis of their relative importance and significance.
