EXPLANATOBY l^OTES. 



To the following tables a few, and only a few, notes of explanation are needed, 

 referring chiefly to abbreviations. 



The letter S. affixed to the name of any substance, or to a determination of 

 specific heat, indicates that the substance was in the solid condition. The letter 

 L., on the other hand, stands for liquid. These signs are used only when for any 

 given substance determinations have been made both in the solid and liquid 

 states. 



When figures indicating any given temperature are appended to a determina- 

 tion of specific heat, they show that the determination applied only to that 

 temperature. When, however, two temperatures are given, as for instance, 

 .0557, 0°-100°, the determination is the mean specific heat between them as 

 extremes. 



Such an abbreviation as m. of ~, m. of 5 1 attached to any determination, indi- 

 cates that it is a mean of #, mean of 5, &c, experiments. 



In referring to authorities more extended abbreviations have to be employed. 

 A single number attached to the name of any authority, refers to the accompa- 

 nying list of papers. Thus, Kopp. 34, refers to Kopp's paper numbered 34, and 

 so on. 



With other abbreviations, as a rule, which refer to periodicals or large works, 

 numbers indicating series, volume, and page are also used. Of course when no 

 number for series is given, the first (or perhaps only) series is referred to. The 

 following abbreviations are employed : — 



A. C. P. "Annalen der Chemie und Pharmacie." 



A. C. Phys. "Annales de Chimie et de Physique." 



A. S. P. N. "Annales des Sciences Physiques et Naturelles." 



C. R. " Comptes Rendus." 



C. S. J. "Journal of the Chemical Society." 



Ed. J. S. " Edinburgh Journal of Science."
