The saponification equivalent for cocoanut oil is thus found to lie 

 between 257—260. 



Saponification equivalent op pure fresh ghee (clarified butter). 



1. 13 '525 gm. ghee were heated in a water-oven and then kept 

 inside a desiccator for a week. The ghee was then found to weigh 

 13'5 gm. It would thus appear that ghee is not hygroscopic ; nor does 

 it contain any moisture. 



1. 1*8196 gm. ghee were treated with 20 c. c. alcoholic potash solu- 

 tion. Details as in the previous cases.
