When Mr. Berthollet made known the combination of 
what w'as then called oxygenated muriatic acid with potash, 
he gave as his opinion, that the proportion of oxygen, rela- 
tively to the quantity of acid, was greater in the salt than in 
uncombined oxygenized muriatic acid. This conjecture was 
fairly founded upon the observation, that, in his mode of pre- 
paring this salt, a large portion of common muriate was formed 
in the liquor, along with the hyperoxygenized muriate. The 
Memoir which he published in the year 1788, is the last with 
which I am acquainted, upon this subject. It does not contain 
any thing that, considering the accuracy which is now required 
in experiments, amounts to a demonstration of the relative 
proportions of oxygen, in oxygenized and hyperoxygenized 
muriatic acids. Unfortunately, this chemist has not pursued his 
researches any farther ; although, from his own words, we had 
every reason to hope that they would have been continued. 
In the Sy steme des Connoissances chimiques of Mr. Fourcroy, 
* I have preferred this word to oxygenated , because ate is the appropriate termi- 
nation of certain salts formed by the acids in ic. Some further remarks upon this 
subject will be made in a work now in th« press, entitled Remarks upon Chemical 
Nomenclature*
