I BEG leave to submit to the Society, an 
account of some experiments for ascertaining 
the quantity of latent heat contained in steam 
at different temperatures. Having lately had 
an opportunity of observing some steam-en- 
gines worked by steam of a high temperature, 
and being told that they were attended with a 
saving of fuel, I was led to inquire the cause. 
There are some mechanical contrivances in 
the construction of the engines that lessen the 
consumption of fuel; but it seemed a question 
worth investigation, whether there was any
