South India Charnockites is situated almost entirely outside 
the limits of the Mysore State into the southern 
which the Charnockites encroach only to a very limited extent, 
and the western fringe of the Coimbatore belt. Yet, even in 
described in the Dharwar area. Where the two great areas 
come nearest to one another, small patches, in the published 
surveys, have been ascribed to the one or to the other in such 
&manner as to convey the impression that the surveyors ex- 
perienced some perplexity in deciding to which of the two 
series they should ascribe some of the smaller outliers. 
A narrow band consisting largely ot quartzites, referred to the 
Dharwars has been mapped by Middlemiss as penetrating the 
Charnockite outcrop of North Coimbatore. It will be referred 
to again in the sequel of this note. In this connection allusion 
may be made once more to the Pseudo-Charnockites forming 
limit of the areas exclusively characterised respectively by 
harwars and by Charnockites.

veyed with sufficient closeness of detail, exhibit outlines quite 
Similar to those of many Dharwar outcrops.
