riority of many of the manufactures of France, and especially the per- 

 fection of the figures, that add so much to the beauty and utility of our 

 works on natural history. The progress made in this art by his lectures 

 is not less due to his character than to his talent ; never was there a 

 more affectionate, a more attentive master, he strove that each of his 

 scholars should rival himself. During the latter years of his life he did 

 not execute any large paintings, but employed his time in making mo- 

 dels, that might gradually smooth away the difficulties to his pupils. 

 The object of his labours was the school he has formed at the Museum ; 

 and whilst admired in foreign countries, the only enjoyment he desired 

 was the favourable opinion of his colleagues and students. 



At the age of seventy-six he still retained all his faculties, and would 

 have rendered us still greater services had he not been suddenly car- 

 ried off, on the nth of May 1822. His chair has been suppressed, and 

 the iconographical course is given jointly by MM. Redoute and Huet, 

 the one taking the vegetable, the other the animal kingdom. 



Twenty days had scarcely elapsed when M. Hairy, from whom his 

 death had been concealed, followed him to the tomb. M. Haiiy had 

 professed twenty years at the Museum ; he is the founder of the French 

 school, and the methods of other countries have been modified by his; 

 perhaps the last age has not witnessed a more remarkable discovery, 

 and one more completely the work of its author, it may be applied to 

 every mineral species, it places mineralogy in the rank of the exact 

 sciences, in determining by a rigorous measure the form of the primitive 

 nucleus, and by subsequent calculations all the resulting secondary 

 forms (1). Once published, this theory could never be lost, but it 

 would have presented many difficulties, had not the professor by the 

 clearness and elegance of his explanations removed such a drawback. 



He not only confined himself to giving his lectures, but he united at 

 his own house those who were fond of the study, displayed to them 

 his collection, and superintended their labours ; his instructions were 

 proportioned to the capacity of the student ; and many foreigners who 



(1) In our description of the rooms containing the minerals, we mentioned that the first 

 armory contained wooden models, serving to render sensible to the eye and at the same time to 

 explain the crystalline structure. We may add here, that these models are the work of M. Belceuf, 

 at present residing in the garden. This artist executes with the most rigorous precision all th e 

 varieties of form determined and described by M. Haiiy He sells at a moderate price complete 

 eels with additional models, representing the principal results of the mechanical division of 

 crystals and {he gradation of decrease giving rise to theni.
