Fraction 1 on hydrolysis yielded an acid which after crystallisation 
from alcohol melted at 54° and was identified as myristic acid. 
0-1002 gave 0-2704 002 and 0-1109 HqO 0=73-6, H=12-3. 
Oi 4H2802 requires 0=73-7 H=12-3 percent. 
The amide crystallised from alcohol in minute needles melting at 102°. 
Fraction II consisted essentially of methyl palmitate since on hydrol- 
ysis it yielded palmitic acid melting sharply at 62°. Fraction III 
which formed the main bulk of the distillate yielded on hydrolysis an 
acid which after crystallisation from alcohol melted at 70° and was 
identified as stearic acid. 
Identification of the Liquid Acids. 
The crude mixture of liquid acids, as separated from the lead salt, 
had an iodine value of 115 and obviously contained acids of a higher 
degree of unsaturation than oleic acid. On distillation under dimin- 
ished pressure (100mm.) the following fractions were obtained

•• 
From a consideration of the iodine values it was obvious that little 
separation had taken place and as further fractionation did not cause 
any alteration in the iodine value, the mixed acids (10 grammes) 
were dissolved in chloroform and treated with bromine until no further 
absorption took place. On removing the chloroform in vacuo a viscous 
semi-solid mass remained. This was ground up with dry ether and 
the residual solid collected, whilst from the filtrate on cooling in a 
freezing mixture a further quantity of solid crystallised. (Yield 1 ’2 
grammes.)* The crude bromo acid melted at 183-185° and after 
efystallisation from acetic acid it was obtained in plates which melted 
sharply at 185° and this melting point was unaltered on admixture 
with a specimen of hexabromolinolenic acid from another source. 
0-1109 gave 0 1646 AgBr Br=63-3. 
Ci6H3o02Br6 requires Br=63-3 per cent. 
* This corresponds with a content of 4-4 per cent, linolenic acid in the mixed 
liquid acids. From the iodine value of the mixture (115) it should contain, assuming 
only linolenic and oleic acids to be present, 10 per cent, of linolenic acid.
