3. Cemhufiion of phofpkoratcd Hidrogen Gas, by the Admixture 



of hyperoxigenifed Muriatic Acid Gas. 

 If phofphorated hidrogen and hyperoxigenifed muriatic acid Flame by mix- 

 gas be mixed together, fire and flame are produced; and tureo tW0 S aes » 

 fimple muriatic acid, water, and phofphoric acid, are formed. 



4. Combujiion of inflammable Subfiances in nafcent hyperoxigenifed 



Muriatic Acid Gas. 



Put into a wine-glafs one part of hyperoxigenifed muriate Numerous com- 

 of potath perfe&ly dry ; pour on it, two of colourlefs fulphuric k * ik ^jjJ^ T * 

 acid of commerce : a violent action will take place, and hy- mU riatic gas: 

 peroxigenifed muriatic gas becomes evolved. If, during the 

 extrication of this gas, one part of fulphuric ether, alcohol, or 

 oil of turpentine, be fufFered to fall into the gas, an accenlion 

 takes place, accompanied with a crackling noife. 



In this manner not only all the inflammable fluid bodies, 

 but likewife raoft of the folids, fuch as camphor, refin, tallow, 

 pitch, elaftic gum, &c. may eafily be inflamed. 



5* Combujiion of exprejjtd Oils at the Surface of Water, by 

 Means of hyperoxigenifed Muriatic Acid Gas. 



Put into an ale-glafs one part of hyperoxigenifed muriate of of oils on water j 

 potafli ; add to it three or four of water, and half a part of oil 

 of olives, or of linfeed. On adding to it four or five parts 

 of concentrated fulphuric acid, a violent action takes place , 

 much charcoal becomes depofited, and a multitude of ignited 

 fparks pafs through the black fluid, exhibiting a beautiful 

 phenomenon. On adding an additional quantity of hyperoxi- 

 genifed muriate of potath and fulphuric acid, the whole mafs 

 takes fire, and burns with a denfe yellow flame. 



6. Combujiion of Phofphorus in hyperoxigenifed Muriatic Acid 

 Gas, under the Surface of JVaUr. 



Let fall into a wine-glafs, or rather into a long cylinder, phofphorus un- 

 filled two thirds with water, one part of phofphorus, and two watcr ' 

 of hyperoxigenifed muriate of potalh. On adding to this mix- 

 ture three or four parts of fulphuric or nitric acid, the phof- 

 phorus takes fire, and burns vividly under the furface of the 

 fluid: on agitating the mixture, ftreams of ignited fparks pafs 

 through the fluid rapidly.
