Coconut oil hydrogenated with 3 per cent nickel is gradually 

 decolorized and deodorized, but apparently does not harden very 

 readily. Hydrogenation for fifteen hours gave a solidified sam- 

 ple having practically no iodine value and a melting point of 

 32° to 41° (Table 7). Coconut oil consists principally of the 

 glycerol esters of lauric and myristic acids and contains also a 

 number of other fats which are the glycerides of other fatty 

 acids, such as caproic, caprylic, capric, and oleic (Table 6). 

 Caproic glyceride is a liquid, while caprylic melts at 8.3° ; caproic, 

 at 31.1° ; and lauric, at 45°. Although these glycerides are satu-
