'Colonel Cullen, also through a similar formation at Baypoor near Ca- 

 licut, and through the strata in favourable situations between these loca- 

 lities, which should be carefully examined for a continuation of the 

 carboniferous bed or basin. 



13. — A description of the geognostic position of the fossiliferous 

 strata between Torioor and Womaloor, near Tattan about 10 miles south 

 of the Pachamalley hills, with specimens. 



14. — Do. of the magnesite formations of Yedichicolum, and other lo- 

 calities in the valley of the Cauvery. 



15. — Do. of the corundum mines, in the same localities, principally 

 at Veralimodos, near Sholasigamany, Cocarambady, in the Permutty 

 taluk; also nearNamcul. Mr. Fischer of Salem, informed me that he 

 discovered a fine ruby imbedded in the corundum at Viralimodos, which 

 was valued at forty pagodas. A description of these localities was ex= 

 pected from the able pen of the late lamented Dr. Benza, and it is to be 

 hoped will be published by his executors, if not in print already. 



16. — On a recent visit to the beryl mine of Pattaley,in the Kanghyum 

 taluk, near Coimbatoor, I was informed by the natives that the beryl is 

 also dug at a place called Vaniambady, at the northern base of the Neil- 

 gherries ; farther information on this subject is desirable, as I cannot 

 hear of this gem existing any where in Southern India except in these 

 two localities. It may assist the observer in his search, to recollect 

 that its matrix, both in Siberia and at Pattaley or Poddioor, is the 

 cleavelandite, 



17. — A description and specimens of a sulphuriferous soil, stated by 

 the natives to occur in the Wodiapolliam jungle, south of Wolandoorpett, 

 Southern Arcot, covering an extent of low swampy ground. Mr. 

 Fischer, to whom specimens were sent, informed me that the sulphur is 

 seen on the surface after rains in a yellowish crystalline form. He 

 also kindly furnished me with a small quantity of the earth, which is 

 friable and of a brown colour. The "Wodiapolliam jungle he describes 

 to be part of a jungly belt that extends, east and west, across the 

 peninsula. 



18. — The tracing of the sandstone and fossiliferous beds of Pondi- 

 cherry, southward of the Gingee river. From the circumstance of speci« 

 mens having been brought me by the natives, I think that the former, 

 and possibly the latter with which it is associated, extends into the 

 Verdachelum taluk of South Arcot, in a S. W. direction. 



19. — A description of the extent, accompanied by a suite of speci- 

 mens, of a bed of shell limestone, which I found between Hyderabad, 

 and the city of Beder, This bed may be a continuation of a similar
