EXPLANATORY NOTES. 



In references to literature the following abbreviations have been used. In each 

 case, as far as practicable, series, volume, and page are indicated, the page reference 

 signifying, according to circumstances, either the first page of the paper cited, or else 

 the actual page upon which the determination is given. The former rule applies to 

 pages containing many data; the latter to cases in which the specific gravity datum 

 is merely incidental.
