DiscrssioN. 



The President remarked that on behalf of the Geological Society, 

 as well as of Indian geologists, he would express his pleasure at 

 hearing a paper on India by an independent observer. He referred 

 to Mr. Foote's view that the auriferous rocks of Mysore differed 

 from the main gneissic group of Southern India. There was no 

 doubt as to the great age of the rocks. The analyses given by 

 Mr. Attwood would be useful. He questioned the Author's use of 

 the word " kunker," which meant a small stone and, in the plural, 

 gravel. As lime is commonly made from calcareous nodules in 

 India, the term "kunker" has gradually but erroneously come into use 

 amongst Europeans for calcareous rocks. There was great interest 

 with regard to the asserted Tertiary age of the porphyrite-dykes, 

 when viewed in connexion with the great volcanic outbursts of the 

 Deccan ; but he would like to have some much more positive evi- 

 dence as regards the age of these intrusions. With regard to the 

 elevation of the Ghats, he doubted its connexion with pressure- 

 effects. The eastern Ghats are more or less imaginary, and the 

 western Ghats simply a ridge left by denudation. 



Mr. ^\. P. Blake observed that the schistose rocks closely re- 

 sembled the auriferous Archsean rocks of the United States, espe- 

 cially those in Dakota. 



The AiTTHOR, in reply, stated that Prof. Bonney agreed that the 

 porphyritic rocks were much more modern than the Archaean schists 

 through which they broke. He had adopted the word " kunker " as 

 he found it used in the particular area described and generally 

 applied to the calcareous deposits.
