IMPORTANT FACTS DERIVED MA. 
THEMATICALLY FROM A GENE- 
RAL THEORY, EMBRACING MANY 
RESULTS IN CHEMISTRY, WHICH 
ARE DENOMINATED ULTIMATE 
FACTS. 
By Thomas Exley, a.m, 
{Communicated to the Chemical Section of the 
British Association, Aug. 23rd, 1836.) 
It is not for one man to build the temple of 
science, many must be employed. 
You, veterans in science, you have collect- 
ed an immense mass of materials. Many 
have digged for a foundation, but every one 
yet examined has proved sandy. It has 
been my lot, through the guidance of the 
Great Architect, to find the rock on which you 
may safely build. 
My object is to place chemistry under the 
domain of mathematical science, and to esta- 
blish my new theory by easy calculation and 
mathematical proofs. 
The two principles, which form the foun- 
dation, are these ; viz. 
1st. Every atom of matter consists of an 
indefinitely extended sphere of force, which 
varies inversely as the square of the distance 
from the centre ; and that this force acts 
towards the centre, and is called attraction 
at all distances, except in a small concentric 
sphere, in which it acts /rom the centre, and 
is there called repulsion.
