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°. 

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

 Wd — specific rotation. 

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

 Sol. p. = solidifying point. 

 M. p. = melting point. 

 B. p. = boiling point, 

 n = normal. 



Acid v. = acid value; ester v. = ester value; sap. v. = saponification value. J 

 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.
