454 ^^ phojphoraled Hydrogen Gas. 



CONCLUSIONS. 



The following are the new properties which I conceive I have been the firft to difcovet 

 in the phofphorated hydrogen gas. 



1. This gas is capable of uniting with diftilled water in the proportionof about one- 

 fourth of its bulk, when the folution is efFefted at about ten degrees of the French 

 thermometer *. 



2. It communicates to the water in which it is diflblvcd a ftrong and difagreeable fmell, 

 as well as a bitter tafte ; which may at feme future period be ufed with fuccefs in the 

 treatment of various difeafes, either from the facility with which this preparation is de- 

 compofed, or on account of the efFeft produced by the phofphorus it contains, in the 

 formation of animal fubflances. 



3. When water, purified of its air, is ufed for the purpofe of diflblving this gas, and 

 if, when thus diflblved, it is carefully preferved in clofely flopped veflels, it may be kept 

 for a long time without undergoing decompofition ; fo that by heating the folution, the 

 whole of the phofphorated hydrogen gas which it contains may be difengaged in the 

 gafeous ftate. 



4. When water has been by this means deprived of the phofphorated gas which it had 

 diflblved, it again returns to its original ftate of purity ; whence it follows that its new 

 properties are derived from the prefence of this gas alone. 



Laftly, this folution is capable of fpeedily reducing feveral metallic oxydes, whether 

 «lone, or diflblved by acids, and of forming with them, by double ele£live attradlion, 

 water and metallic phofphurets : which combinations have only hitherto been obtained 

 in the dry way only; that is to fay, by heating metals with phofphorus, or rather by 

 the decompofition of phofphoric glafs, or metallic phofphates, by means of metals and 

 carbon.

BEG leave to prefent to the Society an account of the under-ground inclined plane, 

 which the Duke of Bridgewater has lately made at Walkden-Moor, between Worfley and 

 Bolton, in Lancafliire. To this account I have fubjoined two plans, with a table of re- 

 ference to each. 



• It is probable that at the temperature of zero, a greater quantity might be diflblved by the water j but 

 for want of a fuflScient quantity of phofphorus, I was not able to afcertain this fact.
