lected branch of Paleontological research, and compares the different forma- 

 tions in respect to the character and abundance of the fossil remains of this 

 class in each. The richest and best preserved Fauna is that in the Amber, of 

 which 1,100 species have been examined, and the number in collections probably 

 amounts to 4,000 species at least. Next to this, in the number of species, seems 

 to come the Tertiary formation, which Heer has done so much to elucidate.
