4 AUTOBIOGRAPHY OF FRANCIS ARAGO. 



From this moment I abandoned the classes of the cen 

 tral school, where I was taught to admire Corneille, 

 Racine, La Fontaine, Moliere, and attended only the 

 mathematical course. This course was entrusted to a re 

 tired ecclesiastic, the Abbe Verdier, a very respectable 

 man, but whose knowledge went no further than the ele
