jj^ Blqgyajflikal Memoir (^M. Ilaii^, 



yicre not of a nature to make him be known. When he went to 

 reside for sonie time in the small town which gave him birth, 

 nonp of his old neighbours could have supposed, from his man- 

 ners, that he had become a considerable personage in Paris. 

 One day, while walking on the Boulevard, he fell in with two 

 old soldiers who were going to fight ; he informed himself of the 

 cause of their quarrel, reconciled them ; and, to assure himself 

 that they would not cast out again, went with them to seal the 

 peace, as soldiers are wont, to the gin-shop. 



This great simplicity of manners would probably have pro- 

 longed his life, notwithstanding the extreme delicacy of his 

 jhealth, had not an accident accelerated his end. A fall which 

 he received in his room broke the neck of his thigh-bone, and 

 an abscess that formed in the joint rendered the disease incura- 

 ble. Purjng the long pains by which his death was preceded, 

 he did not cease to manifest that benevolence, that pious sub- 

 mission to the decrees of Providence, that ardour for science, 

 which characterized his life. His time was divided between 

 prayer, the revisal of the new edition of his work, and his inter- 

 est for the future lot of the pupils who had aided him in com- 

 posing it. 



M. Haiiy died on the 3d June 1822, at the age of seventy^ 

 nine, leaving to his family the single but magnificent heritage of 

 that precious collection of crystals of all varieties, which the 

 gifts of almost all Europe for twenty years had carried to a de- 

 gree of perfection which is unrivalled. 



His successors were, in the Museum of Natural History, M. 

 Brongniart ; in the Faculty of Sciences, M. Beudant, and in this 

 Academy, M. Cordier. These gentlemen are three of his pu- 

 pils. In fact, and this will form the last circumstance which we 

 have to adduce in his praise, it would be difficult to find, at the 

 present day, in Europe, a mineralogist worthy of the name, who 

 has not become so, if not directly, at least through an assiduous 

 study of his works and discoveries.
