COMBINATION OF OXIMURIATIC GAS AND OXIGEN. £71 



The smell of the pure explosive gas somewhat resembles Smell of the 

 that of burnt sugar, mixed with the peculiar smell of oxi- 

 muriatic gas. Water appeared to take up eight or ten Solubility, 

 times' its volume; but the experiment was made over mer- 

 cury, which might occasion an errour, though it did not 

 seem to act on the fluid. The water became of a lint ap- 

 *proachingto orange. 



When the explosive gas was detonated with hidrogen Attractioa of 



equal to twice its volume, there was a great absorption, to oximunatic 



, t I . t> .... „ - gas for hid(0- 



more than f, and solution of muriatic acid was formed ; gen. 



when the explosive gas was in excess, oxigen was always ex- 

 pelled, a fact demonstrating the stronger attraction of hi- 

 drogen foroximuriatic gas than for oxigen. 



I have said that mercury has no action upon this gas in Action of the 

 its purest form at common temperatures. Copper and an- ^"jajg" " 

 timony, which so readily burn in oximuriatic gas, did not 

 act upon the explosive gas in the cold : and when they 

 were introduced into it, being heated, it was instantly de- 

 composed, and its oxigen set free; and the metals burnt in 

 the oximuriatic gas. 



When sulphur was introduced into it, there was at first sulphur, 

 no action, but an explosion soon took place : and the pecu- 

 liar smell ofoximuriateof sulphur was perceived. 



Phosphorus produced a brilliant explosion, by contact phosphorus, 

 with it in the cold, and there were produced phosphoric acid 

 and solid oximuriate of phosphorus. 



Arsenic introduced into it did not inflame ; the gas was arsenic, 

 made to explode, when the metal burnt with great brilli- 

 Hucy in the oximuriatic gus. 



Iron wire introduced into it did not burn, till it was iron, 

 heated so as to produce an explosion, when it burnt with a 

 most brilliant light in the decomposed gas. 



Charcoal introduced into it ignited, produced a brilliant charcoal, 

 flash of light, and burnt with a, dull red light, doubtless 



vity of pure oximuriatic gas from manganese and muriatic acid is to that oximuriatic 

 of common air, as 244 to 100. Taking this estimation* the specific gra- gas, 

 yiry of the new gas will be about 238, and the number representing the 

 proportion in which oximuriatic gas combines, from this estimation, will 

 ha rather higher than is stated above,
