Oil from the seeds of Calophyllxim inophyllnm. The seeds contain 

 22*8— 31*5 H 2 and 50*5—55 oil per* cent. The oil has a yellowish-green 

 colour, an odour resembling fenugreek, a bitter taste, and, on keeping, 

 fatty glycerides are deposited. It solidifies at 8°, melts again at 8°, and 

 has a sp. gr. 09428 at 15°, Reichert-Meissl number 0'13, saponification 

 number I960, acid number 28*45, iodine number 92*8, refracto-meter 

 number 76 at 40°; it contains 0*25 per cent, of unsaponinble matter. 

 The increase in weight due to oxygen absorption, when measured by Livache's 

 method, amounted to 0*25, 0*71, 1*32, and 1*84 percent., after 18, 40, 64, and 

 136 hours. Treatment with 5 per cent, soda solution removes the resinous 

 constituents. The purified oil solidities at 4°, melts again at 8°, and has 

 Reichert-Meissi number 0'18, saponification number 191, iodine number 86. 

 The fatty acids of the oil are chiefly palmitic, stearic, and oleic. J. Ch. S. Vol.

The seeds are brownish black, almost spherical, |— 1 inch in diameter and 

 consist of an easily-broken shell surrounding a round, soft, whitish kernel 

 which weighs about 4 grins. The kernels contain L3 per cent, of moisture and 

 55 per cent, of viscous, green, bitter oil. 



Some samples of kernels from Bengal contained 3' 3 per cent, of moisture 

 and 71-4 per cent, of oil having the Sp. gr. at 15° C. O" 950 ; acid value 45'9 ; 

 Saponification value, 193-203 ; iodine value, 97*7. 



The oil is excellent for soap making. The residual cake is bitter and 

 therefore suitable for use as a manure.
