’l^ Mr. Chenevix’s Observations and Experiments 
country frequently contains in solution, and which is precipi- 
tated from it by water. Before we assert a fact, we should be 
well assured of the pureness of our chemical agents. This 
supposed conversion of muriatic or hyperoxygenized muriatic 
acid into nitrous gas, will not pass for a decomposition, or a 
transmutation, of that refractory radical; and the idea of the 
change of potash into lime, is as, erroneous as some other late 
assertions respecting the decomposition of the alkalis. 
The proportions of this salt are, as I before stated, 
Hyperoxygenized muriatic acid - - 58,5 
Potash - - - - - 39,2 
Water - - - 2,5 
1Q0,0, 
2 d Species. Hyperoxygenized Muriate of Soda. 
This salt is prepared in the same manner, and with the same 
phenomena, as the former. It is extremely difficult to obtain it 
pure, as it has nearly the same degree of solubility in water 
as muriate of soda. It is soluble in three parts of cold, and 
less of warm water ; and is slightly deliquescent. It is soluble 
in alcohol ; but this property alone is not sufficient to enable us 
to obtain it free from the muriate of soda, formed along with it 
in the entire liquor ; as the latter salt, contrary to the assertions 
of all authors, is soluble in alcohol, and seems to be much more 
so, when accompanied by the hyperoxygenized muriate. It was 
by taking a large quantity of the entire salt, formed by sending 
a current of oxygenized muriatic acid gas through a solution of 
carbonate of soda, and repeatedly crystallizing in alcohol, that, 
with great difficulty, I obtained a little pure hyperoxygenized 
muriate of soda. It crystallizes in cubes, or in rhomboids lit®.
