 necessity of keeping the skins so long in the pits, he asked 

 himself with scrupulous anxiety whether leathers prepared in

 guarantee them to the shoemakers, who were unanimous in 

 praising the goods of the little tannery-yard, but alas equally 

 unanimous in forgetting to reward the disinterested tanner by 

 prompt payment? He supplied his family with the neces- 

 saries of life : what more did he want? When he had news 

 of his Normalien he was thoroughly happy. He associated

1 Institut de France. Name given collectively to the five following 

 societies 



1. Academie Fran$aise, founded by Richelieu in 1635 in order to 

 polish and maintain the purity of the French language. It is composed 

 of forty Life members, and publishes from time to time a dictionary 

 which is looked upon as a standard test of correct French. 



2. Academie des Inscriptions et Belles Lettres, founded by Colbert in 

 1G63. 



3. Academie des Sciences, also founded by Colbert in 1666. It has 

 published most valuable reports ever since 1699. 



4. Academie des Beaux-Arts, which includes the Academies of Paint- 

 ing, of Sculpture, of Music, and of Architecture. 



5. Academie des Sciences Morales et Pqlitiques. 



It was in 1795 that these ancient academies, which had been sup- 

 pressed two years before by the Revolution, were reorganized and com- 

 bined together to form the Institut de France. [Trans.]
