GEOLOGICAL SECTION. 
The Geological Section held its usual two meetings, despite the darkened 
streets of the city. The first lecture was by Mr. F. T. Maidwell, of Runcorn, 
on ‘“‘ The New Red Sandstone System of Cheshire,’”’ and was of great interest 
to those knowing the Bunter and Keuper of the district. The second, on “ The 
Erosive Work of Ice in Nature,’’ was given by the honorary secretary of the 
Liverpool Geological Society (Mr. T. A. Jones). A review of modern theories 
on glaciation and its resultant surface features, this proved to be most instruc- 
tive to a large audience. Some very beautiful Alpine views illustrating the 
subject matter were shown. (See also report on inside back page of cover.) 
NATURAL PHILOSOPHY SECTION. 
SOME DEVELOPMENTS OF MODERN CHEMISTRY. 
Lecture delivered October 12th, 1916, by Mr. A. H. Cooper, M.S8ce., B.A., 
of Wrexham, 
_-‘The lecturer traced the gradual change in the methods of chemical research 
from the early days of the alchemist, when empirical and but little understood 
methods were employed, and the chief aims of the exponents were the mystifica- 
‘tion of the uninitiated and the pursuit of the “ philosopher’s stone,’ which 
should turn the baser metals into gold; and showed how the modern chemist, 
with the help of the atomic theory, could now proceed, by a series of reasoned 
experiments based on sure knowledge, to discover the composition of bodies 
and to build up in the laboratory substances identical with natural products.
