different from cubes. It produces a sensation of cold in the 
mouth ; and its taste is easily distinguished from muriate of soda. 
It is depomposed by heat, by combustible bodies, and by acids, 
in the same manner as the former species ; and the acid holds 
its place for soda, as for potash, immediately before the benzoic. 
The basis is separated by potash only. This salt is composed of, 
Hyperoxygenized muriatic acid - - 66,2 
Soda - - - - Qg,6 
Water - 4/2

3 d Species. Hyperoxygenized Muriate of Barytes . 
The earthy bases seem to follow, in the order of affinities for 
this acid, at a great distance from the alkalis. They are all 
superseded by the two just mentioned ; and it is much more dif- 
ficult to accomplish their union with the acid, than is the case 
with potash or soda. The most advantageous method is, to pour 
warm water upon a large quantity of this earth, procured by 
Mr. Vauquelin’s method ; and to cause a current of oxygenized 
muriatic acid to pass through the liquor, kept warm ; so that 
the barytes already dissolved being saturated, a fresh portion of 
it may be taken up by the water, and presented in a state of 
great division to the acid. This salt is soluble in about four 
parts of cold, and less of warm water. It crystallizes like the 
muriate of this earth; and resembles it so much in solubility, 
that I could not separate them effectually by crystallization 
repeated several times. At first, indeed, I despaired of ever 
obtaining any of the earthy hyperoxygenized muriates in a 
state sufficiently pure for analysis. If we consider them as a 
genus distinct from the alkaline hyperoxygenized muriates,
