GENERAL REMARKS. 
prussic, and the zoonic. In all these the other characters 
of acids are likewise exceedingly feeble. The strength of 
the acid taste differs exceedingly in those which have it. 
In some, as the sulphuric, it is intolerably strong ; in 
others, as the boracic and the succinic, it is barely per 
ceptible ; while in others, as those which have a metal 
lic basis, it is overpowered by an acrid metallic savour. 
All the acids are soluble in water ; but in this re 
spect also they differ exceedingly from each other. Six 
of them are so soluble in water that they have never 
been obtained except in combination with that liquid: 
These are, 
5. Sebacic, 
3. Acetous, 
1. Sulphuric, 
6. Loonic. 
4. Prussic, 
2. Nitric, 
The rest may be obtained either in the state of gas, or 
in a solid or crystallized form. Five of them are gases, 
which are readily absorbed by water to a certain a 
mount, after which the water being saturated refuses to 
absorb any more. The weight of each absorbed by 
100 parts of water may be seen in the following TABLE. 
1. Muriatic . 100.00 
2. Sulphurous .. 3.96 
3. Carbonic...... 0.18 
4. Oxy-muriatic......... unknown 
5. Fluoric ............. unknown 
The weight of the remaining acids, when solid or 
crystallized, soluble in 100 parts of water, is exhibited 
in the following TABLE.
