gas, and the least proportion is formed by sulphuretted 

 hydrogen. Their solid contents are constituted by the 

 neutral salts of lime, magnesia and soda, carbonates and 

 sulphates. 



"In a little pamphlet, by 'A Physician of Philadel- 

 phia," I find iron mentioned as present, " sufficient to 

 strike a deep blue with the Prussiate of potash." I think 

 this is a mistake, and find no evidence whatever of the 

 existence of iron, either by reagents or by the taste ; it 

 is clearly a non-chalybeate. At the Hot Springs, five 

 miles hence, they are decided chalybeates, with a tem- 

 perature of 101° F. As to the proportions, you know 

 it would not be becoming in me, at present, to give any 

 statement of that kind ; a man must be a very expe- 

 rienced analist to do that with a good face. Crystals of 

 epsom salts are found formed in various places by the 

 spray of the waters. 



" The waters resemble those of Aix la Chapelle, with 

 which I am familiar. Nothing can exceed the beauty 

 of this water to bathe in ; the large bath is so very pel- 

 lucid, and has such a highly refracting power, that 

 really it presents one of the most admirable and amusing 

 spectacles possible, and produces the most delicious 

 sensations; the bubbles of gas escaping and sporting 

 over your body like little fishes. The larger and fatter 

 the person, the greater the enjoyment. 



" The temperature of this bath is about 97° or 98°. 

 At the Hot Springs I found waters at 102°."
