Identification of the liquid acid. 
The liquid acid had an iodine value of 80‘1 and on distillation under 
diminished pressure yielded the following fractions : —

Fraction IV crystallised almost completely on keeping and was 
found to consist of stearic acid. The main fraction (II) was almost 
pure oleic acid which, however, from the analytical data obtained, con- 
tained a trace of an impurity which was not removed by redistillation. 
The barium salt after crystallisation from moist benzene was analysed. 
0-2386 gave 0-0816 BaS 04 Ba=20-0. 
Cse Hec O 4 Ba requires Ba=19-6 per cent. 
A sample of the acid regenerated from the barium salt had the follow-

ing constants : — ^ 0'89, 1‘458, iodine value 88’8. Analysis 
indicated that it still contained some impurity. 
0-0922 gave 0-2548 COj and 0 0996 H^O, C=75-4, H=12-0. 
Ci 8 H 340 ii requires C=76-6, H = 12-l per cent. 
The silver salt was also analysed. 
0-2411 gave 0 0687 Ag Ag-28-.5. 
CisHssOjAg requires Ag=28-4 per cent. 
The nature of the impurity present could not be determined 
nor could any liquid acids other than oleic acid be detected in 
Fractions I and III. 
Summary. 
Garcinia Camhogia seeds yield 31 per cent, of a fat resembling in 
its general properties the fats from other species of Garcinia. It 
should prove an excellent edible fat. 
2. The acids present in the form of glycerides were identified as 
stearic and oleic acids.
