ADDRESS OF THE COUNCIL.

ing facts in Zoology and Botany must remain obscure, 
and that the Sciences of Geology, Mineralogy, and 
Meteorology, would be altogether unintelligible. So 
strongly indeed does this impression seem to have 
been felt by the gentleman who favoured the Society 
with a Lecture upon Geology, that he occupied a 
considerable portion of his Lecture with a concise 
and rapid sketch of the first principles of Chemical 
Science. To remedy this deficiency, therefore, and 
to place the Members and Friends of the Society in 
such a situation, as should enable them hereafter 
to comprehend without difiiculty those details of the 
several branches of Natural History which require 
a knowledge of Chemistry for their illustration, the 
Council thought, and they trust correctly, that a 
Course of Lectures upon Chemistry, illustrated by 
appropriate experiments, would prove acceptable to 
the Society. They therefore gladly availed themselves 
of Dr. Thomson's liberal offer of assistance, and trust 
that the Society will cordially acknowledge their 
debt of gratitude to that gentleman for his very 
interesting experimental Course of Lectures upon 
that elegant and instructive Science, 
Communications. 
It now only remains for the Council to state the 
arrangements which have been made with respect 
to the communications and papers laid before them.
