406 MR. A. K, COOMARASWAMY ON THE (Aug. 1902, 
About 300 yards or so north of Talatuoya, on the Gurudeniya 
minor road, the road-cutting on the east side of the road exposes a 
series of normal granulites, among 
which a band of limestone 8 feet 
wide is intercalated, there being a 
northerly .dip of about 50°. A 
transition-zone 14 to 2 feet wide is 
seen on the north side, the southern 
boundary being less clearly exposed. 
North of this zone are normal granu- 
lites; south of it the rather rotten, 
coarsely crystalline limestone, dotted 
with dark pyroxene. Sections from 
the outer part of the transition- 
zone show a rock much like an 
ordinary, rather acid, pyroxene - 
Kandy-Talatuoya road.
