Mr.- Hatchett’s Analysis, &c. 
to dryness, the whole was put into a crucible coated with char- 
coal, as above described. The crucible was then placed in a 
forge belonging to Mr. Chenevix ; and a strong heat was kept 
up for half an hour. 
The inclosed matter was spongy, and of a dark brown ; it in 
some measure resembled phosphuret of titanium. 
After this, we wished to try the effect of a still greater heat ; 
but in this experiment the crucible w 7 as melted. 
The above experiments shew, that the white oxide, like 
several other metallic substances, may be deoxidated to a certain 
degree, without much difficulty, but that the complete reduction 
of it is still far from being easily effected.
