OILS OF SEA URCHIN AND MAR FISH K<i<,.

with CC1 4 chloroform, ether, and acetone. From its appearance 

 on standing it seemed to behave somewhat as a semi-drying oil. 

 8.3 grams of oil was obtained from 183 million eggs. The iodine 

 number as determined by the Wijs method was 146-148, and the 

 saponjjifiation value (Kottstorfer value) approximately 606.0. 



The I 2 value is suggestive of the marine animal oils such as 

 Menhaden and Sardine oils, also the liver oils. The high 

 saponification value confirms the results of the volatile acid 

 determination presented in Table I. It also suggests that much 

 of the oil represents fatty acids of low molecular weight. 



The fatty acids volatile with steam were determined by the 

 method of Dyer (2). Twelve million Arbacia eggs were used. 

 The results of the steam distillation of star fish eggs is also 

 included. 9,160,000 of these eggs were distilled. Three hours 

 and forty minutes were required in both cases for the distillation. 



TABLE I. 



DYER METHOD FOR STEAM VOLATILE FATTY ACIDS OF Arbacia AND Asterias. 



6,000,000 Asterias eggs == 2.474 cc. N/io NaOH. 

 6,000,000 Arbacia eggs = 2.000 cc. N/io NaOH. 

 Since the Arbacia eggs = 75 p. in diameter and Asterias eggs 

 = 1*04 fj. in diameter.
