Historical Eloge of M. Vauquelin. 213 



death of Fourcroy, he took charge of his sisters, who were 

 poor, aged, and diseased, as he would havfe ddne of his own 

 mother. For their sakes, he renounced the pleasure of having 

 a family of hisoWHi^^'d^ they remained till their death in his 

 nouse, the objects of Ills most tender and anxious care. 



After what has been said, it will be perceived that a great 

 part of M. Vauquelin''s eloge must be that of M. Fourcroy ^ ; 

 arid accordingly we have there spoken of their great experiment 

 J^ur la Composition de TEmi par la Combustion du Gaz Hydros 

 ghie^ ; of their united labours Sur rUrk^ ; on the Diff^ 

 rents Esphes de Calculs*; and ConcrStions Animates et Veg^* 

 tales ^ ; of their Analyse des Os ^ ; of their Recherches sur le^ 

 Combinaisons de VAcide Sulfureux '^; Sur la Strontiane ^ ; Sur 

 les Metaux unis an Platine^; Sur V Arragonite^^ ; and nume- 

 rous other substances belonging to the three kingdoms : and, 

 finally, the numerous experiments by which they sought to esta- 

 blish the new theory of Chemistry ; of all of these we have al- 

 ready spoken in such a manner as to preclude the necessity of 

 reverting to them. 



In these writings, upwards of sixty in number, the reader at 

 once recognises the extended views of Fourcroy, and that de- 

 sire to attempt and know every thing which formed one of the 

 characteristics of his mind, combined with the coolness and un- 

 ostentatious but always ingenious activity by which Vauquelin 

 assisted him in attaining his object.
