ture of 10° for 24 hours,and then the liquid was filtered. The 
filtrate was decomposed with dilute hydrochloric acid, washed, and 
the ether evaporated off in a stream of dry carbonic acid. The 
unsaturated acids obtained in this way gave an iodine value of 84. 
They were almost colourless, havin g a faint yellow tint, and remained 
liquid at the temperature of the laboratory, which was about 
17° Centigrade. Compared with the acids left after trituration 
with alcohol ‘911, the amount was not large. 
e lead salts, insoluble in ether, were also decomposed with 
hydrochloric acid and washed and dried. The acids were then 
added to the mixed fractions from trituration with alcohol men- 
tioned above. This mixture then contained all the saturated 
fatty acids.
