cases the scapolite is sometimes granular, but more often it forms 
plates enclosing the other minerais which sometimes assume graphic 
forms. Sometimes there are numerous elongated inclusions arranged 
parallel to the vertical axis.!

(8) Lron-Ores.-—Pyrite in small quantity is. a common accessory 
mineral in the limestones ; and is sometimes abundant also in the 
mineral-aggregates, but it 1s not usually characteristic of these. 
It may occur as a definite contact-mineral, as in the quarry 2 miles 
north of Nalanda. 
Magnetite is occasionally met with; it was noted in some quantity 
in a variety of limestone from the western quarry at Gettembe. 
Dr. Schiffer’s examination of pyrite from Wattegama” showed its 
composition to be pure FeS,, and he noted the forms (111) and (210). 
(9) Clinohumite was found at Gettembe, 3 miles west of 
Kandy, and at Ampitiya, 3 miles east of Kandy. At Ampitiya yellow 
granules of clinohumite were found in coarsely crystalline limestone 
about a fifth of a mile north-west of Ketawala trigonometrical station. 
At Gettembe three pits have been opened for hme-burning, north 
of the road and below the hill (‘ Primrose Hill’). The middle pit is 
disused and small. Yellow clinohumite is very abundant in one
