and massive conglomerates of local rocks. These rocks 

 occur in tlie Eastern Ghauts. 



4. Devonian. — The Yindhyan series, principally sandstones, 



distributed into four groups. 



5. Carboniferous. — (a) Mountain -limestone of the Salt 



Range, classified as such from the fossils collected by 

 Dr. Flemning. 



(b) The Talcheer series, sandstones of a peculiar 

 character and colour, resting on a " boulder bed," or 

 ancient shingle beach. 



(c) The coal-bearing rocks of India, forming the coal- 

 fields of Damuda, Nerbudda, &c. 



6. Permian ? or intermediate. — Beds with reptilian remains, 



representing, in Dr. Oldham's opinion, the physical break 

 between the Palaeozoic and Mesozoic periods of Europe. 

 We have ventured to indicate it here as doubtfully 

 Permian. 



7. Triassic — Upper and Lower. In this latter there are beds 



of Hmestone with Geratites (Muschelkalk ?). 



8. Rh^tic Beds — with characteristic fossils. 



9. Liassic Group — divided into an Upper and Lower Series. 



10. Jurassic Group — with Cycadese. Divided into Upper, 



Middle, and Lower Stages. 



11. Cretaceous Series — with fine forms of Ammonites and 



other shells. 



12. Eocene. — (a) Nummuhtic limestones. 



(b) Fresh-water deposits of lakes ; over, and through, 

 which sheets of lava have been erupted. 



13. Miocene. — " Laterite," and other strata of several kinds. 



14. Pliocene. — Ossiferous Gravels, Clays, &c. 



15. Recent. — Gravels, Clays, and Mud of Rivers, &c. 



It is impossible to look over the above great series of beds, so 

 truly representative as they are of the European system, and pre- 

 senting often in minute detail a marked correspondence with our own 

 subdivisions and formations, without being struck with the wonder- 

 ful uniformity of Nature's operations in ancient times over vast 

 portions of the globe. The stratigraphical resemblances are also 

 not less remarkable than the palaeontological, for the genera and 

 some species of fossils of the Triassic, Liassic, and Cretaceous form- 

 ations are identical with those of Europe. 



The metamorphic origin of granite gave rise to a lively discus- 

 sion, and several geologists pressed forward to niake a public recan- 

 tation of the erroneous doctrines they had once maintained on a 

 subject on which some light was thrown during the discussion of 

 Dr. Bryce's paper " On the Granites of Arran." The author
