EXPERIMENTS MADE WITH THE VIEW OF DETERMINING THE RELA~ 
TION BETWEEN MURIATIC ACID AND CHLORINE. 
To the inferences which I have ventured to draw, from the 
experimental results detailed in the preceding part of this pa- 
per, two objections may be offered. 
First, That the aqueous product obtained in the decomposi- 
tion of dry sal ammoniac, by ignited metallic laminze, may pos- 
sibly be derived from the azote of the ammonia, supposing azote 
not to be a distinct elementary substance, but a peculiar oxide 
of hydrogen. This notion occurred to me at an early period, 
in consequence of the anomalous, and unaccountable disap- 
pearance, of a portion of ammonia, and the concomitant pro- 
duction of water, as described in my experimental researches 
on the ammoniacal salts. ‘To determine how far this view was 
correct in the present instance, I made the following experi- 
ment: Into a tube of green glass, sealed at one end, I put 
30 gr. of desiccated sal ammoniac. Over it 200 gr. of pure 
iron turnings were placed, which occupied 5 inches of the. 
tube. The open end of this was connected by a collar of 
caoutchouc, with a narrow tube of crystal glass, having a small 
: sphere
