X PUBLISHERS' NOTE. 



now prosperous Kepublic, will be recognized as in 

 all respects appropriate by every reader of the work 

 of the earlier Sadi Carnot who is familiar with 

 the character, the history, the attainments, the 

 achievements, of the later Sadi Carnot in so 

 many and widely diverse fields. The Carnot 

 talent and the Carnot character are equally ob- 

 servable in both men, widely as they are separated 

 in time and in the nature of their professional 

 labors. Both are great representatives of a noble 

 family, whose honor and fame they have both 

 splendidly upheld. 



The Publishers offer this little book to its 

 readers as a small, yet in one sense not unim- 

 portant, contribution to the great cause of modern 

 science, as a relic, a memorial/a corner-stone.
