boiled and filtered ; the solution was then evaporated to dryness 

 and ignited, when a residue of alkaline chlorids was obtained. 

 The presence of soda was shewn by the peculiar color imparted 

 to the flame of alcohol when it was burned over the salt, and 

 with chlorid of platinum, a bright yellow precipitate of platino- 

 chlorid of potassium was obtained. 



In a water so novel in character, we might be led to expect 

 some metal not usually present in mineral springs, and I have 



accordingly given the details of the qualitative analysis, to shew 



the measures taken to detect their presence. Arsenic, antimony, 

 tin, lead and copper have all been recently detected in different 

 ferruginous waters of Europe, but the presence of free sulphuret- 

 ted hydrogen, which is found in the recent water of the present 

 spring, is incompatible with their existence in solution, at least 

 after the small quantity of this gas which it contains, had been 

 decomposed by exposure to the air.

The quantity of sulphuretted hydrogen present is small, being 

 about one-half of a cubic inch in 200 cubic inches of the water. 



The question of the origin of this spring presents such difficul- 

 ties, that I will not attempt to speculate upon it ; the fact that the 

 spring issues directly at the roots of a pine not yet wholly de- 

 cayed, is evidence that it has not existed for a very long period, 

 at least with its present character; for as it has been remarked, no
