ANALYSIS OF THE SPRING CALLED THE CHA- 

 LYBEATE WEAK SALINE WELL. 



L Physical Characters of the Water, 



.J. HE taste of this water is slightly saline and soft. It is 

 perfectly limpid, and destitute of smell. It sends forth a few 

 air-hubbles, bnt not in any remarkable quantily. Its tem- 

 perature was 54^ Fahr. ; the surrounding air being GO", and 

 llie barometrical pressure G0"7. Its specific weight at that 

 temperature was as 2S9'4 to 289. The spring which fur- 

 nishes this water ri?es in the area on the east side of Hygeia 

 Hi)ti8e. Its bed is.A-M'ifr bkie^-^'-, abounding with extra- 

 rtous fossils, chiefly of the bivalve kind, wholly converted 

 jn_.taxlaV^; jDie (T^h of this well is 36 feet. It yields 150 

 gallons of water in 24 hours. 



ir. Examination by Re-agents. 



Experiment I. — Tincture of cabbage is reddened by this 

 water. 



Experiment IT. — Tincture of galls produced no effect. A 

 slice of a t.ut-gall suspended in the wat-^r highly concen- 

 trated and previously mingled with a few drops of nitric acid, 

 occasioned a purplish hue. 



Experiment III. — Succinate of ammonia aT\(.\ prussiafe of 

 poiw^h when ap])lied in a similar manner occasioned a pre- 

 cipitate. Water that had been boiled and suffered to stand 

 undisturbed and then decanted, when treated with the same 

 tests remained unaltered. 



Experiment IV. — Lime-ivater mingled with this water in 

 equal quantities became cloudy : muriatic acid rendered the 

 mixture transparent.
