Part III.] Gopal Rau and Simonsen : Oils and Fats from seeds. 9 
The oleic acid separated from the barium salt was foimd to distil 
at 280-282° 100mm. (uncorr.) and had the following constants-: — ' 
Df^o 0'889, 1’4583, iodine value 90'0. 
The solid acids (11 grammes), separated from the lead salts which 
were insoluble in ether, were fractionally converted into the magnesium 
salt by means of magnesium acetate in alcoholic solution when the foll- 
owing fractions were obtained : —

From the above results it is clear that the solid acids present con- 
sisted of approximately equal parts of stearic acid (M = 284) and pal- 
mitic acid (M=256). No other acids could be detected. 
Summary. 
The seeds of C. Wightianum yielded on expression 34 per cent, of an 
oil which resembled closely the oil obtained from the s^eds of C. Inoph- 
yllum. 
2. The oil contained about 10 per cent, of resin. 
3. The acids present in the form of glycerides were stearic, palmitic, 
oleic and linolic acids.
