List of abbreviations, 

 d = specific gravity. 



d 2 oo = specific gravity at 20° (in references from our laboratories uniformly compared 



with water at 15°). 

 d^ = specific gravity at 20°, compared with water at 4°. 

 «D2oo = optical rotation at 20°, in a 100 mm. tube. 

 [«] D = specific rotation. 

 n D 2oo = index of refraction at 20°. 

 sol. p. = solidifying point, 

 m. p. = melting point, 

 b. p. = boiling point, 

 n = normal, 



acet. = acetylation. 



acid. v. = acid value; ester v. = ester value; sap. v. = saponification value, 

 g. = gram; cc. = cubic centimeter; mm. = millimeter. 



Temperatures are uniformly given in degrees Centigrade. 

 The strength of alcohol, if not otherwise indicated, is given in per cent, by volume.
