PROCEEDINGS 
OF THE 
PERTHSHIRE SOCIETY OF 
NATURAL SCIENCE. 
WINTER SESSION, 1898-99, 
10th November, 1898. 
Henry Coates, F. R. S. E., President, in the Chair. 
The President delivered the following Opening Address:— 
Gentlemen, —During the months which have elapsed since the 
close of our last winter session the work of the Society has by no

our membership. One practical outcome of this movement has

in the Free Library, and to express the hope that this may be but 
the beginning of a career of friendly co-operation and mutual help¬
