Ci 5 H 2 6O the acetylation number would indicate that 

 the alcohols form 23.22 per cent of the total weight of 

 the oil. 



The complete analysis shows that the oil contains the 

 following constituents in the given percentages:

ALCOHOLS (eudesmol, globuol, with traces of free acids 



and esters) 23 



In order to determine whether or not the oil from 

 the burrs, which are necessarily gathered in large 

 quantities with the leaves, had any detrimental effect 

 upon the oil as a whole, a quantity of the burrs were

collected, ground and steam-distilled. The yield of 

 oil corresponded to 0.2 per cent of the weight of the 

 burrs. The oil thus obtained was of a lighter specific 

 gravity and had a greater rotation than the leaf oil; 

 it dissolved in 18 volumes of alcohol (70 per cent by 

 weight) while the leaf oil dissolves in 15 volumes. 

 This would seem to indicate that the burrs have a
