These fats were only slightl} T browned. Mr. Mory found that cotton- 

 seed oil was veiy easily affected and the titer lowered to a considerable 

 extent. In investigating the effect of sulphuric acid on the freed acids 

 it was found that the titer was not changed. Mr. Mory also made a 

 number of interesting determinations showing the effect of remelting 

 the fatty acids prepared b} T the Dalican method, and b} r heating to 

 150 C., as a method of drying, instead of drying four hours at 105 C. 

 The fatty acids are placed in a beaker and heated to 150 C., stirring 

 constantly. The figures given in Table V do not show any material 

 effect from heating, at least where the Wolfbauer method of stirring 

 was used. Table VI shows the effect of remelting the fatty acids pre- 

 pared by different methods of saponification.
