The granular structure of these masses, especially if there is slight 
decomposition, causes them to shatter at a light touch of the 
hammer, so that it is sometimes difficult to collect specimens for 
slicing. 
There are also occasionally to be found in the limestones, quite 
isolated, inclusions of pyroxene-granulite a few feet or yards in 
width ; and it may happen that the foliation of the limestone bends 
around them, suggesting flow-structure. Such occur, for example, 
on the Bandarawela road, beside the road, between the 563 and 
57 milestones, and elsewhere in the Hakgala district (Pl. XIV). 
Sections from the central portions of the bands and masses here 
mentioned possess the usual characters of the pyroxene-granulites, 
the minerals augite, plagioclase, orthoclase, quartz (one case only), 
amphibole, brown mica, magnetite, pyrite, and sometimes sphene 
and scapolite, being noted. 
Inclusions of quartz-rock, similar to that commonly occurring 
among the granulites, are exceedingly rarely met with. In one 
or two cases, strips of quartz an inch or two wide were noted in 
association with, or forming part of, the pyroxenic inclusions. 
Bands of quartz-rock (with also a negligible quantity of pyroxene) 
an inch or two wide were noted in limestone in the bed of the 
Talatuoya, four-fifths of a mile north of the bridge at Talatuoya. 
On the Hakgala map (PI. XIV) it will be seen that some large 
ellipsoidal masses of rock belonging to the Charnockite Series are 
completely included in the limestone-bands, and there are others. 
smaller. In several cases these consist of a coarse quartzofelspathic 
rock; in other cases ordinary acid granulites enter into the com- 
position of these masses, which L regard as masses of intrusive rock 
in the limestone, less flattened laterally than is usually the case. 
The exposure described by Mr. Parkinson’ is seen in the railway- 
cutting south of the level-crossing, south of Matale railway-station. 
I have visited the section, and am in complete agreement with 
him (except that I cannot find here or elsewhere in Ceylon clear 
evidence of an augite possessing the pleochroism of hypersthene,. 
my own sections of the ‘band’ exhibiting only the usual green 
augite). The cutting shows a horizontal band of pyroxene- 
eranulite, with crystalline limestone above and belowit. The band 
becomes laterally very rich in pyroxene, and is not sharply separated 
from the limestone. It is probable that there has been, as 
Mr. Parkinson supposes, some absorption of calcareous material at 
the junction. 
It will be useful to refer in greater detail to two other localities 
in which bands of acid granulite or pyroxenic granulite are found 
in the limestone.

little north of the belt of acacias, and above and west of the Hakgala 
footpath, is a small section showing crystalline limestone with a
