 (very rare), £2. 2s 1824 



This celebrated work first contains the author's theorem so well known as ' Carnot's Cyclb', and laid the foundation 

 of the science of thermodynamics. ' Carnot is now recognised as one of the greatest, scientific men of the century; and 

 had he survived, there i.s no doubt that the theory of heat would have been established nearly 30 years earlier than it was. 

 Carnot's methods, as given in his book, were not appreciated till Lord Kelvin in 1848 drew attention to them. The novel 

 feature of his method was the invention of the cycle of operations, and especially the reversible cycle, etc. etc.'— 

 Prof. Knott.
