appearance than this takes place. It is, that a pre- 
cipitate, seemingly like the former, has been made 
by the addition. of muriatic acid: but by the addi- 
tion of more acid the precipitate is re-dissolved. 
Sometimes, indeed most commonly, I have not 
been able to effect thisappearance. - 
It was natural to expect the solution of any fur- 
ther uncommon observation in the same matter which 
had already explained so much. 3. I accordingly 
digested sulphat of lime in the hepatised solutions 
of iron and manganese; and I found that the latter 
had a very strong-solvent power. After the liquor 
had been filtered, sulphat of lime was plentifully pre- 
cipitated by sulphuric acid. The solution of iron 
seems to have something of a similar property; but 
as it is very small, and as iron has almost always a 
little manganese united with it, it is, at least, uncer- 
tain whether the whole effect ought not to be attri- 
buted to manganese. 
‘It remains to compare this remark with the effects 
of the artificial oxygenated salts; and thus to confirm, 
if any confirmation were needed, the analogy which 
I have laboured so much to establish. 4. Sulphat 
of lime was digested with the oxygenated muriat of 
manganese and distilled water by a gentle heat: af- 
ter twenty-four hours the clear liquor was separated: . 
ror the more unaccountable, as Bergman has expressly re- 
marked this decomposition in his Dissertation on the Ana-« 
lysis of Waters, See Dissertation 11. 7. M,
