They require probably the following formulae, Fich- 
telit C 5 H 4 , Hartit C 6 H 5 , Tekoretin CH, Phylloretin C 3 H 2 . 
Though the numbers obtained by the analysis of 
Fichtelit by Bromeis indicate a different formula, yet 
we are disposed to consider it identical with the sub¬ 
stance which we have analyzed; for they both occur 
under the same circumstances and in the same turf beds; 
and moreover they have a common melting point. Fich¬ 
telit also distills without being decomposed, and behaves 
towards alcohol and ether as does this resin. 
The difference in composition, indicated by the ana¬ 
lyses , may perhaps be accounted for by the fact that 
Bromeis analyzed Fichtelit just as it was obtained from 
the wood, without recrystalising it, hence it was neces¬ 
sarily impure. 
Rather than increase the confusion already existing 
in the nomenclature of these and allied substances, we 
shall adopt the name given by Bromeis. 
We should not forget to notice that Trommsdorff 
has also analyzed a fossil resin coming from Redwitz 
and found under the same circumstances, in the stems 
of Pinus sylvestris ; and having the same outward appea¬ 
rance as Fichtelit, but in its melting point, 107° C., and 
in its composition it differs greatly; viz.

Carbon 91.05 
Hydrogen 7.57.
