DEDICATED

TO

Sadi Carnot,

President of the French Republic,

That distinguished member of the Profession of Engineering whose whole Life has been an Honor to his Profession and to his Country;

AND WHO, ELEVATED TO THE HIGHEST OFFICE WITHIN THE GIFT OF THE

French Nation,

has proven by the quiet dignity and the efficiency with which he has performed his august duties that he is a worthy member of a noble family, already rendered famous by an earlier Sadi Carnot, now immortal in the annals of science, and is himself deserving of enrolment in a list of great men which includes that other distinguished engineer, our own first president,

GEORGE WASHINGTON.
