In the above vee there is uncertainty as to the presence of 
stearic acid, and owing to the method adopted for the separation 
of the fatty acids it appeared desirable to make a separation 
ab initio by means of the lead salts and redetermine the iodine 
— for the unsaturated acids. Be pest a fresh lot of the 
fatty acids was saponified. The soap was converted into 
as Tad? salts saa these treated according to the method of Tor- 
telli and Ruggeri. The solid and liquid acids were thus separated. 
The liquid acids on standing for a few days at 18° had deposited a 
few small needle-like crystals which melted or dissolved in the 
liquid acid on slightly warming it. These are mentioned below.

melting point of each fraction was found to be 64°.5. Sin
