 the right, is deposited a small and beautiful head of Ichthyo- 

 saurus tenuirostris : and below, a specimen of Ichthyosaurus 

 latifrons. 



E. [5.] An interesting example of Ichthyosaurus tenui- 

 rostris is placed in the upper division. In the lower, there

MINERALS. 



TABLE-CASE 1. [37.] One half of this table is set apart for 

 silicates containing glucina and alumina, the principal species 

 of which is the Beryl, including the Emerald, a gem which 

 owes its green colour to oxide of chromium. The other part 

 of the table is occupied by oxides of Titanium and titanites.
