24 Analysis of the lately discovered 



prussiatc of lime produced any change when added to the 

 water; but when a lew grains of nitrous acid and oxy-niu- 

 riate of potash were previously dissolved in it, a blue'preci-' 

 pitatc was then obtained. 



From these preliminary observations we are led fo be- 

 lieve, that this water contains carbonic acid, oxygen gas, 

 salts with a base of lime, salts with a base of maonesia, with 

 oxidc of iron, with sulphuric acid, with muriatic acid, &c. 



Examination of the Gaseous Contents of the 

 Water. \ 



92-1 cubic inches of the saline water, freslf taken from 

 the spring, were introduced into a retort connected with 

 the mercurial trough. The water was made to boil, and the 

 gaseous products collected over mercury. After the appara- 

 tus had again acquired the temperature which prevailed at the 

 commencement of the operation, it was found, by the addi- 

 tion of barytic water, that 48-28 cubic inches of carbonic 

 acid gas h.id been disengaged, of which 12-7, therefore, are 

 contained in one gallon of water. The residuary caseoiis 

 fluids, on being examined by the test of phosphorus and 

 by the action of hydrosulphuret of lime, were found to be 

 composed of 4*84 parts of atmospheric air and 16-12 parts 

 of oxygen gas. Hence the gaseous contents of one gallon 

 of the saline water are : 



Cubic inches. 



Carbonic acid gas - 12-07 

 Oxygen gas - - 4-03 

 Atmospheric air - i-2l 



17-31 



ANALYSIS. 

 Experiment I. — 924 cubic inches of the saline water beinfr 

 evaporated in a glass retort to eight cubic inches, were re- 

 duced to dryness in a glass bason at a temperature of 224"^ 

 Fahr. The mass was of a brilliant white colour; it tasted 

 strongly saline and bitter. Its weight amounted to 2296 



grains.
