b. The Singhalese call it Gandagangalle. (Sulphur stone.) 

 Found at Bogodde near Ampitte. 



This substance has externally the colour of Sulphur, dispersed 

 through a deep and beautiful shade of green ; it is very soft and when 

 moistened is saponaceous to the feel, at the same time leaving a green 

 colour in solution on the finger. Strong sulphuric acid dissolved it, at the 

 same time making it a very light shade of yellow ; before the blowpipe 

 it became a black hard mass, and gave off no fumes of Sulphur whatever. 



c. Found at Hewalgolla near Gallaboddaallata Yhaliwa. 

 Resembles marble, and is almost of as fine a grain, but not so purely 



white : it is Dolomite. 



d. The Singhalese call this Yoda atte' (Giant's bones). 

 According to their tradition it is the bones of two giants who 

 fought and perished at the place where this mineral is found ! 



It is Limestone from deposition ; it does somewhat resemble a decayed 

 bone externally, but a slight examination determines its real origin. 



e. Magnetic Iron ore. 



Found at Yatte Kohila and Arrapasse on the road to 

 Katragam. 



A very fine sample of Magnetic Iron ore. 



f The Singhalese call it Nilgarrunda gal; rubbed with 

 turmeric a red colour is produced ; it is used as an antidote 

 against snake bite. Found at Garrandegalle near Walapane. 



A variety of tourmaline, but not of a very compact structure. 



g. Found at Dickkapitteagodde. 



Are large crystals of black opaque tourmaline. 



k. Found at Mahatellagodde near Dickkapittea. 



Is a variety of mica slate. 



i. Sf j. Found at Arrapasse, on the road to Katragam. 

 Varieties of Hornblendic rock, one is of a green shade, and when 

 treated with strong sulphuric acid, it gave off strong fumes of Chlorine. 



The Secretary presented to the Society a specimen of 

 Pyrites which he procured at the last Horticultural Show, 

 from the Modliar of the Sina Korle, from whose district it was 

 brought ; on examination of the specimen it was found to be 

 auriferous, though in a very small degree.
