P. MACNAIR ON ROCKS OF HIGHLAND PERTHSHIRE. 189 
n6C6SSciry for us to go back upon sonic of the earlier work done 
amongst these rocks; for, as we have shown, many of our later 
views upon the geological structure of the southern Grampians had 
already been anticipated by earlier geologists. It will also be apparent 
from what has been said that we have by no means as yet reached 
that final stage of knowledge, in which the complicated puzzle of 
the structure of Highland Perthshire lies unravelled in all its parts. 
Much still remains to be done, and it is to be hoped that the 
members of this Society will not be behind in the fascinating work 
which lies ready to their hand. Your reward is sure, for ‘ Nature 
never did betray the heart that loved her.”
