12 /. Lawrence Smith on the Thermal Waters of Asia Minor. 



is probably crenate of lime, A slight odor of sulphuretted hydro- 

 gen, not perceptible when the water is cold. The taste of the 

 water when cold is in no way peculiar, and it is very pleasant 

 to drink. Specific gravity 1-00118. Temperature, (atmosphere 

 at 66^ Fah.,) 182^ Fah., which varies but a few degrees with the 



seasons. 



Chemical Composition, — The gas which escapes from the 

 source was collected in inverted bottles, well corked and sealed, 

 and in one thousand parts was found to contain 



Carbonic acid, . 



Nitrogen, 



Oxygen . • . 



Sulphuretted hydrogen.

Solid contents in one litre of the water, 970 grammes. The water 



is alkaline, and, when concentrated to one third its bulk, gives a 

 very sensible alkaline reaction with reddened litmus paper. It is 

 found to contain the following ingredients in one litre : 



Carbonic acid, free,* 



Carbonic acid, fixed, 



Hydro-sulphuric acid, 



Sulphuric acid, .

There are some portions of the incrustation richer in organic 

 matter than this, but then the mixture is sensible to the eye, and
