the hydrochloric acid, which cannot be separated from water 
by heat when it is mixed with it in small proportion. The 
hydrochloric acid was then precipitated by nitrate of silver. 
The chloride of silver obtained had notwithstanding a black- 
ish colour, from a slight mixture of sulphuret of silver. The 
results of this analysis were: Antimony 1:937 gramme (29°9 
grs.), and chloride of silver 6°886 grammes (106°3 grs.), equi- 
valent to 1699 gramme (24°7 grs.) of chlorine. The chloride 
of antimony then is composed of

If I had obtained the chloride of silver quite free from sul- 
phuret of silver, this result would agree much more with the 
calculation. 
- Ifa current of dry chlorine is made to pass over heated 
metallic antimony, another chloride of antimony is ob- 
tained. The antimony burns vividly in the gas, emitting 
sparks, whilst a very volatile liquid is formed. ‘This liquid is 
white, or of a very light yellowish tint; it also contains chlo- 
ride of iron, if the antimony employed contained a portion of 
this metal.. The chloride nevertheless remains at the bottom 
of the vessel, and does not dissolve in the liquid. This resem- 
bles, in all its external characters, the fuming spirit of Liba- 
vius ; it has a strong and disagreeable smell, and fumes in the 
atmosphere. When exposed to the air, it attracts water and 
changes into a white mass, in which white crystals form, which 
afterwards dissolve without rendering the solution milky. 
- This phenomenon is caused by a property of the liquid chlo- 
ride of antimony, (which it possesses in common with the 
fuming spirit of Labavius,) of forming a crystalline mass when 
mixed with a little water. 
The liquid chloride of antimony heats strongly when mixed 
with a greater quantity of water ;. it becomes milky, and a pre- 
cipitate is formed having the properties of hydrated antimonic 
acid. Heated gently, it gives off water and becomes yellow- 
ish; but at an elevated temperature it becomes white. The 
liquid contains hydrochloric acid. As the liquid chloride of an- 
timony is changed by water into the hydrochloric and antimo- 
nic acids, which last contains 5 atoms of oxygen to 1 of anti- 
mony, it follows that this chloride contains 5 atoms of chlo- 
rine to 1 of antimony, or
