Chemical Analysis of Cretaceous Amber from Kreischerville 1 



By Arthur Hollick 



Specimens of amber from the Androvette pit at Kreischerville 

 were subjected to chemical analysis by Dr. William J. Gies of 

 Columbia University, at my request, and he reports that the 

 material is typical amber or succinite, so far as chemical composi- 

 tion is concerned. Amber oil, containing succinic acid, was 

 obtained by destructive distillation, and a number of determina- 

 tions of elementary composition yielded the following data: 



Carbon 77-87 



Oxygen 12.57 



Hydrogen 9.11 



Sulphur 0.35 



Ash 0.10 



100.00 



Volatile matter at ioo° C 0.40 



(Nitrogen and phosphorus absent.) 



which agrees with the data relating to succinite as determined by 

 various observers.
