i 30 Utility of Oxygenated Muriatic Acid in Scarlet Fever i 



was made so as not possibly to contain either lead or any 

 other metallic substance. 



To prepare the oxygenated muriatic acid in a perfect state 

 of puritv, put two ounces, bv measure, (?f distilled water 

 into a narrow tubulated bottle with a ground glass stopple ; 

 into this gradually pour, by measure also, as much muriatic 

 acid, the specific gravity of which is as 1 170 to 1000 of di- 

 stilled water, frequently shaking the vial } add then to it 

 two drams of oxymuriate of potash *, which in a little time 

 will fall to the bottom, the acid seizing the small portion of 

 alkali, and liberating beautiful globules of vital alir^ which 

 slowly rise towards the surface, diminishing as they ascend, 

 superdxvgenating the acid : a little agitation now and then 

 facilitates the process, but it will be three or four days be- 

 fore the acid becomes hyperoxygenated : the stopple should 

 be put loosely into the vial and tied over with a piece 

 of bladder^ but not too tight, allowing it to move when 

 the gas is rapidly extricated. This process should be per- 

 formed in a dark situation, and the oxygenant medicine 

 be after preserved, by putting over the bottle a circular piece 

 of pasteboard, to prevent it from being injured by the de- 

 oxvgenating power of light* 



it is not in scarlet fever onlv that this preparation pro- 

 inises to be of advantage j I have found it useful in angina 

 maligna and oilier diseases proceeding from or producing a 

 deo~xygenatlon of the blood : in many lingering cases of the 

 late influenza it was exhibited with evident advantage, iii 

 the doses above mentioned. 



From the trials made by Guyton Morveau artd others, 

 it appears that the oxvgenated muriatic acid in a gaseous 

 fofitl possesses the power of neutralizing and destroying 

 contaffiotls miasmata, even in rooms where the sick are 

 present, without the slightest inconvenience. Possessed of 

 amazing expansibility, this gaseous oxygenant diffuses itself 

 over the most extensive apartments, leaving nothing un- 

 touched, and touching nothing it does not appropriate} 

 rapidly oxidating metallic bodies, particularly iron and steely 

 (which should be removed,) and radically destroying the 

 most offensive odours, thereby rendering Innocuous perhaps 

 deadly contagious poisons. 



To completely purify any apartittent, where a patient suf- 

 fers in the scarlet fever or any other contagious disease, so 



'* The be3t Oxymuriate of potash I ever had, was made by Mr. Hoyle, 

 an ingenious chemist in Manchester ; loo grains yielding nearly 7+ cubic 

 inches of oxygen gas.
