These tests were taken on different days, when there was a different degree 
of humidity in the air, and when the temperature of the room was different. It 
was noticed also that the rate at which the gas burned had a decided influence 
on the economy of the operation. A rate of from six to twelve feet per hour was 
used, but the medium between these was probably most efficient. The amounts 
of water evaporated by the coal were as follows:

The only satisfactory method of using the apparatus is to test it first by the 
use of gas, and then under the same atmospheric conditions to test it with the 
coal. Hence, although the above tests seem to differ greatly, they do not differ 
so much when taken in connection with the corresponding gas test, made at the 
same time. 
From the above tests, as we have ascertained the amount of water that one 
cubic foot of gas will evaporate and the amount of water that one pound of coal 
will evaporate, it is not difficult to calculate the value of one ton of coal in terms 
of gas. The results are as follows:

The experiments above noted were made with the ordinary illuminating gas. 
This gas, delivered to the consumers of the city of Lawrence, Kan., on December 
6, 1894, had at that time the following composition:
