This compound has been isolated by other observers as a con- 

 stituent of Personne's " Cannabene." 



Constituents of fraction (c). 



When fraction (c) was allowed to stand crystals separated ; 

 these were found to be sparingly soluble in alcohol, and were thus 

 readily separated. Analysis shewed the substance to be a higher 

 paraffin, and since the melting and boiling points of the substance 

 agree with those which can with considerable certainty be pre- 

 dicted for normal-nona-kosane there is some probability that the 

 compound is this hydrocarbon.
