On the Liquefaction of Chlorine and other Gases. By M. Fara- 

 day, Chemical Assistant in the Royal Institution.* 



I took advantage of the late cold weather (Feb. and March, 

 1823), to procure crystals of hydrate of chlorine for the purpose 

 of analysis. The results are contained in a short paper in the 

 Quarterly Journal of Science, vol. xv. Its composition is very 

 nearly 27*7 chlorine, 72*3 water, or 1 proportional of chlorine, 

 and 10 of water. 



The President of the Royal Society having honoured me by 

 looking at these conclusions, suggested, that an exposure of the 

 substance to heat under pressure, would probably lead to inte- 

 resting results : the following experiments were commenced at 

 his request. Some hydrate of chlorine was prepared, and being 

 dried as well as could be by pressure in bibulous paper, was 

 introduced into a sealed glass tube, the upper end of which was 

 then hermetically closed. Being placed in water at 60°, it 

 underwent no change ; but when put into water at 100°, the 

 substance fused, the tube became filled with a bright yellow 

 atmosphere, and, on examination, was found to contain two fluid 

 substances : the one, about three-fourths of the whole, was of a
