II. On Metallic Titanium. By W. H>. Wollaston, M. D .

Read December 12, 1822. 
The evidence that we yet possess of the reduction of titanium 
to its metallic state, is not altogether satisfactory ; for even 
Laugier, (who has described a valuable series of experiments 
made upon it in 1814, and who had the advantage of all the 
previous knowledge acquired by the labours of Vauquelin 
and Hecht, in 1796, of Lowitz, in 1798, and of Lampadius, in 
1803), could only say that he thought himself justified in 
considering certain parts of his product which were of a gol- 
den colour as really reduced ; adding in confirmation, that 
Messrs. Vauquelin and HAUY,to whom he had shown them, 
“ appeared disposed to adopt his opinion.”* 
As M. Laugier had not the means of confirming his opi- 
nion by analysis, I may presume that an account of some 
experiments which I have recently made upon this substance, 
will be acceptable to chemists in general ; and that in pro- 
portion to the degree of doubt they may entertain, they will 
feel interested to examine scrupulously the evidence I shall 
adduce as to the metallic state of the subject of my experi- 
ments, 
* Je me crois fonde a regarder cette couche mammelonnee comme la portion 
reellement reduite 
M. M. Vauquelin et Hauy m’ont paru disposees a adopter cette opinion.
