260 CHELTENHAM WATER. 
It chiefly contains oxide of iron (21), chalk, carbonat of 
magnesia, Epsom salt (199), sulphut of lime (193), and common 
salt, and a great proportion of carbonic acid gas, or fixed air. 
It is very hard. 
Pyrmont is a town of Westphalia, and about thirty- 
eight miles south-west of Hanover. It is the capital of 
a county, has a strong fort, and is well known on ac- 
count of its mineral springs. 
The water which issues from these springs constantly 
emits so large a quantity of gas as to have a sensible 
pungency of smell to those who stand around, and 
even to make the water-servers giddy. It forms an 
atmosphere over the surface of the well which proves 
fatal to ducks and small birds that attempt to swim 
across. The gas contained in the water is estimated to 
be nearly equal in bulk to the water. It is owing to 
this, that Pyrmont water, if bottled and well corked, 
and afterwards removed into a warm place, will fre- 
quently burst the bottles. 
When drawn fresh from the spring and drunk copi- 
ously, it produces a temporary kind of intoxication. 
It also enlivens the spirits and increases the appetite. 
This water is sent in bottles, by the Weser, to Bremen, 
whence it is exported to various parts of the world. 
296- CHELTENHAM WATER is a saline, carbonated, 
chalybeate, zohich has a slight sulphureous smell, and a brackish, 
somewhat bitter, and chalybeate taste, but no briskness nor 
pungency. 
Its foreign contents are Glauber's salts (293), muriat and 
carbonat of magnesia, common salt, and oxide of iron, together 
with a portion of carbonic acid gas, and some other kinds of gas. 
The original discovery of the mineral spring at 
Cheltenham was about the year 1716. The water of 
this spring issues slowly, and in a scanty stream of not 
more than 35 pints in an hour, from a bed of sand in- 
termixed with blue clay. The well is sunk to the 
depth of six feet, and is excluded from communication
