Was supposed to be scheererite. The other woods oceurring 
with this pine (P. sylvestris) are the same as those of Redwitz 
and Utznach. ‘he resin found by Steenstrup was shown by the 
analysis of Forchhammer to be composed of two carbo-hydro- 
gens, and both quite distinct from scheererite. They were sepa- 
rated by dissolving in boiling alcohol and allowing to crystallize. 
Tekoretin, being less soluble than phylloretin, crystallized first. 
The former melts at 45° C., the latter at 87°

covered in the three localities which have been mentioned, we 
Perceive, that in each place a fossil resin occurs which melts at 
45° or 46° C.—viz., Fivhtelite described by Bromeis from Red- 
witz, scheererite (?) by Haidinger from Utznach, and tekoretin 
by Forchhammer from Holtegard. The relation which they
