at the height of about 150 feet above the level of the 
sea, and contain organic remains resembling those of the 
blue clay of the London and Hampshire basin. 
Mr. Scott has also discovered at Robagiri, in this same 
district, a stratum of white lime-stone containing nummu- 
lites and vertebrae of fish, surmounted by beds of clay 
which contain the same nummulites, and also bones of fish, 
with shells of Ostrea and Pecten. 
Near Silhet the Laour Hills, composed of white lime¬ 
stone loaded with nummulites, form another example of 
tertiary formations in the eastern extremity of this pro¬ 
vince. And the section near Madras, given by Mr. Ba- 
bington, shows the same tertiary formations to exist also 
on the western shores of the Bay of Bengal. 
All these circumstances taken together, leave not a doubt 
of the important fact, that the tertiary strata, which a few 
years since had been noticed only in the basins of Paris and 
London, are most extensively distributed over the surface 
of the globe. Their existence is now familiar to us in al¬ 
most every state in Europe, particularly in the sub-Apen- 
nine formations, where they have been so ably described 
by Brocchi, and are now receiving further illustration 
from the able hand of Professor Guidotti of Parma. 
Again, we trace them round the shores and in the islands 
of the Mediterranean, at Montpellier and Nice, at Savona, 
Volterra, and Rome,—in the fish-beds of Mount Lebanon, 
—and the nummulite limestone that forms the foundation 
of the Pyramids of Egypt. We recognise them also along 
the northern shores of Africa, and in Malta, Sicily, and 
Sardinia. Mr. Strangways has traced them largely in the 
Steppes of southern Russia, and on the shores of the Black 
Sea and the Caspian.* The Russians in their expedition
