Analysis of the Water of the South Spring* 



The water of this spring has a taste similar to that of the 

 other, but rather weaker : it produces similar medicinal effects. 

 In the present state of the spring, its strength is more vari- 

 able, according to the state of the weather. From this circum- 

 stance, and from its being rather weaker, it has probably a 

 greater intermixture of surface-water, or of the water of other 

 springs. When taken up after continued dry weather, it af- 

 forded, by evaporation, 42 grains of solid matter from a pint ; 

 the other affording, at the same time, 47 grains. Its specific 

 gravity was found to be 1.00419. It was in this state, the 

 strongest in which it was found, that it was submitted to the 

 following examination. 



The application of re-agents produced the same appearances 

 as with the water of the North Spring, indicating, therefore, 

 the presence of the same ingredients. To determine this 

 with more precision, and to ascertain the proportions, the same 

 methods of analysis were employed which had been used with 

 regard to the other. Tt will be sufficient to state the results by 

 one method, — the second of those before described. 



A pint of the water was submitted to evaporation, and af- 

 forded of dry matter, weighed while warm, 42 grains. This 



was
