man was dreadfully wounded, and was near losing his sight : by drop- 

 ping the salt into sulphuric acid there is less danger of explosion at 

 the beginning ; but still the acid does not come over without decom- 

 position. By cooling the first receiver with ice, the author thinks that 

 he has obtained the acid in the form of little orange -coloured octahe- 

 dral crystals. 



Nitric acid produces nearly the same phenomena. 



Muriatic acid decomposes the salt, and takes a part of the oxygen 

 from the hyperoxygenized muriatic acid, and becomes oxygenized. 



Phosphoric, tartareous, oxalic, arsenic, and citric acids decompose 

 this salt with the help of heat. 



Some attempts were made to combine diamond with oxygen, in the 

 humid way, by means of this salt and this acid ; but they did not 

 prove successful. Caloric is mentioned as a considerable ingredient 

 in this as in all hyperoxygenized muriates. 



The proportions of the salt are, 



Hyperoxygenized muriatic acid 58'3 



Potash 39-2 



Water 2-5 



100-0 



The second species is hyperoxygenized muriate of soda. This salt 

 Mr. Chenevix obtained pure by crystallizing in alcohol. It is de- 

 composed by the same agents as the former species. It is deliques- 

 cent. Its proportions are, 



Hyperoxygenized muriatic acid 66' 2 



Soda 29-6 



Water 4*2 



100-0 



A distinguishing character of the earthy hyperoxygenized muriates 

 is their resemblance to their respective muriates, in point of solubi- 

 lity. The author at first despaired of being able to separate them 

 from the muriates which accompany their formation ; but phosphate 

 of silver afforded him the means. Phosphate of silver decomposes all 

 simple muriates, and the hyperoxygenized muriates remain alone in 

 solution. It was thus he obtained them pure enough for analysis. 

 He found the following proportions in each salt : 



Third species. Hyperoxygenized muriate of barytes. 



Hyperoxygenized muriatic acid 47'0 



Barytes 42'2 



Water 10'8 



100-0 

 Fourth species. Hyperoxygenized muriate of strontia. 



Hyperoxygenized muriatic acid 46 



Strontia 26 



Water 28
