water freezes more readily than pure water, but the pure 

 gas dried by muriate of lime undergoes no change whatever, 

 at a temperature of 40 belo>w o° of Fahrenheit. The mis- 

 take seems to have arisen from the exposure of the gas to 

 cold in bottles containing moisture;

 Oximuriates of I heated lime gently in a green glass tube, and passed 

 phosphorus the phosphoric sublimate, the saturated oximuriate of phos- 

 phorus through it, in vapour; there was a violent action 

 with the production of heat and light, and a gray fused 

 mass was formed, which afforded, by the action of water, 

 muriate and phosphate of lime, 



I introduced some vapour from the heated phosphoric 



sublimate into an exhausted retort containing dry paper 



tinged with litmus; the colour slowly changed to pale red.
