Our connections with zoological collections and institutions 

 of natural history have rendered it necessary to draw 



\Paleontology 



into our sphere of activity. In this connection we would call 

 attention to our stock of Fossils of the Tertiary Period. 

 From the Mayence basin (diluvium and tertiary) we have 

 remains of mammals such as Elephas, Mastodon, Diustherium, 

 Hippotherinm, Paleomeryx, Aceratheritim, Halitherium etc. 

 of which we can furnish a special catalogue. We also beg 

 to call attention to the fragmentary scales of Glyptodon cla- 

 dipes Osw. from the S. -American Pampas formation. Besides 

 the above we have a fine selection of fossils from the Litho- 

 graphic slate of Solenhofen, from the Swabian Jura (Ichthyo- 

 saurus, Pentacrinus etc.) from the Bohemian silurian etc. 



We are glad to buy suitable material or to effect ex- 

 changes. In this regard also we would request directors of 

 Museums, Academies and Colleges, and likewise private col- 

 lectors, scientific explorers etc. to enter into communication 

 with our institution.
