THE BATIIING AND DRINKING ESTABLISHMENTS. 83

The gas of the sources is composed, in one hundred parts, of

Carbonic acid . . 2,00

Oxygen .... 6,44

Azotic gas . , . 91,56

100,00

The specific gravity of the water is 1004; disfilled water being set = 1000. It is perfectly clear and limpid, and cmits no smell; in taste it reseinbles weak cliicken-broth. Upon the stones rising above the level of the basins, an alcaline salinaceous crust is deposited, one draclnn of wliich contains

19,5 grains of chloride of soda,

1,8

— — sulphate of soda,

0,8

— — carbonate of soda, and

6,0

— •—• carbonate of lime.

The gas eliminatcd from the water upon boiling, con- sists, in one hundred parts, of

Carbonic acid . . 12,50

Oxygen .... 8,25

Azotic gas . . . 79,25

showing a smaller proportion of Oxygen to Azotic gas, than

that existing in

common water, wliich always contains at-

mospheric air in solution.

The last analyse by Professor Degen, executed in 1837, indicates a very slight difference in the quantity of solid and volatilc ingredieuts present in the waters. The results of his investigation were as follows, viz.
