Suspicion of i3>EVERAL years ago, M. Vauquelm indicated an ana- 

 analogy be- , , \ . , , . . , , 

 tween oisanlte ^^§7 between oisanite and titanium ; but as his oppor- 



and titanium, tunities at that time permitted him to make experiments 

 upon small quantities only of the oisanite, and the crys- 

 talline form seemed inimical to his conjecture, an uncer- 

 tainty remained which rendered him desirous of repeating 

 his analysis upon a larger scale. It was not till the pre- 

 sent year, that by making an excursion into Oisan, he 

 was able to procure a sufficient quantity of that substance 

 for his purpose. 



Suspecting that the difference of form and specific gra- 

 vity between titanium and oisanite might depend on 

 the state of oxidation^ he heated equal quantities by the 

 same fire ; but no change was produced in either sub- 

 stance. He simply remarked that the titanium became 

 more decidedly red, which was owing io a small quantity 

 of iron contained in it. 



They have the Titanium and oisanite comport themselves in the same

It cannot be doubted but that these substances really 



combine together, because it is impossible to separate them 



by water or by any other mechanical means. In this 



state of combination with alkali, tlie two substances are
