the productive Era, while the great development of 

 Millstone Grit in Ireland furnishes the term " Hibernia," 

 and the celebrated Adelsberg grotto or cave in Mountain 

 Limestone suggests the term " Austria," as appropriate 

 for that Era. So also Perm- Russia, because the Per- 

 mian system prevails so extensively from Kasan to the 

 Gulf of Tscheskala, near the White Sea ; Trias-Germania, 

 because the Germans have given to all geologists the sub- 

 division of that system (Bunter, Muschelkalk and Keuper) 

 also Jura-Gallia, because the system prevails largely, and 

 has been studied minutely in France. This plan of no- 

 menclature would also serve to recall to the geologist, 

 and convey to the student, important tacts regarding the 

 distribution of the formation. 



5. Somewhat in the same manner, uniformity might be 

 given to the names of nonfossiliferous rocks, by adopting 



Dr. Dana's orthography, as given in his latest works, 

 where he employs the letter " y " instead of " i " as in 

 Granyte, to disiinguish rocks from minerals with names 

 ending in " ite." Even the final " e " may as well be 

 omitted in order to unify for other languages ; and we 

 then have, for example, Granyt, Syenyt, etc., or we may 

 even so apply the rule as to have international names for 

 Limestone, Sandstone, Magnesian limestone and the like, 

 calling them Calkyt, Silikyt, Dotomyt, etc. Some Ger- 

 man scientists (see Cotta's " Gesteinslehre ") use, for in- 

 stance, the word Quartzit, writing it however with an " 1.' 



6. It is thought further that, in many cases, geological 

 terms might be abbreviated, so as to be readily intelligible 

 in all languages, somewhat on the symbolic system 

 adopted in chemistry. A conspectus of the proposed 

 modifications in geological nomenclature, with a column
