the samples under investigation failed 

 to do this to any appreciable or material 

 extent, methods other than the usual 

 ones had to be employed. 



It was at first supposed that an oxid- 

 ized and thus hardened fixed oil had been 

 employed. The most searching exam- 

 ination, however, failed to find even a 

 trace of nickel, which in the form of 

 nickel dust or nickel oxide is usually 

 employed as a catalytic agent in the 

 oxidation of oils. Neither was any other 

 metal found to be present and which 

 might have been employed in a similar 

 manner. 



The author, after numerous trials pre- 

 liminary, finally decided to ascertain the 

 solubility of the substances (pure and 

 adulterated), in absolute alcohol and 

 glacial acetic acid. The former was de- 

 termined in a sealed tube,, in accordance 

 with the method of Lewkowitsch. In 

 the latter case it was found advisable to 

 subject the mixture of glacial acetic acid 

 and Hquid cacao butter, to constant stir- 

 ring during the entire operation. 



The author states that he will furnish 

 the exact details of the methods em- 

 ployed, in the near future, for publica- 

 tion m the columns of the Chemischen 

 Revue ueber Fettund Harzindustrie. 

 Both the temperature of solution and 

 that of beginning congelation were care- 

 fully read and are given in a table. 



From the figures obtained, it may be 

 deduced that without doubt some foreign 

 glyceride was employed as the adulterant. 

 This deduction was further verified by 

 determining the melting point of the 

 glycerides obtained by fractional crystal- 

 lization, from a mixture of 3 parts of 

 absolute ether and i part of absolute al- 

 cohol. The glyceride obtained from the 



si>urios samples possess a melting point 

 ^'f 39-5"4o" C, while that of the glycer- 

 ide obtained from a ])ure sample, and in 

 a like manner, melts at 50-57.4° C.
