green. Heated in a close vessel, it sublimes and condenses in 
long snow-white needles. Sulphuric acid dissolves it, forming 
a yellow liquid, precipitating on the addition of water. Its 
taste is peppery, and its odor peculiar and disagreeable. 
The results of its analysis are: 
I. 0.456 chloride gave 0.133 water and 0.892 carbonic 
acid. 
II. 0.500 of the same gave 0.156 water and 0.372 carbonic 
acid. 
III. 0.400 of the same gave 0.116 water and 0.778 carbonic 
acid. 
To determine the quantity of chlorine, the chloride of sali- 
cyle was decomposed, by passing its vapor over red hot 
lime. 
I. 0.645 chloride gave 0.591 chloride of silver. 
II. 0.600 same gave 0.536 chloride of silver. 
Its composition, by calculation, would then be: 
C 28 1070.16 54. IS 
H 10 62.40 3.16 
O 4 400.00 20.25 
CI 2 442.65 22.41

Chloride of salicyle combines directly with alkalies and me- 
tallic oxides. The combinations with potassa obtained by dis- 
solving with heat the chloride in a solution of potassa of 45.° B. 
yields on cooling, a radiated mass of red plates. 
It is combined with baryta, by double decomposition with 
the foregoing salt. It is a yellow, crystalline powder, and 
seems to be composed of C 28 H 10 4 C1 2 -fBaO. The following 
result agree with composition: 
One product gave for 
I. 0.765 mater. 0,273 sulphate of baryta. 
0.032 " 0.627 chloride of silver. 
Another product gave for 
II. 0.421 matter, 0.204 sulphate of baryta. 
Which is in hundredths—
