The results of the previous experiments indicate the pre- 

 sence of 



Soda, Lime in small proportion, 



Muriatic acid. No magnesia, 



Sulphuric acid, No iron. 



Carbonic acid. No potash. 



A. To ascertain the proportion of sulphuric acid, sixteen 

 ounces by measure, previously saturated by acetic acid, were 

 treated with muriate of barytes ; the precipitate, washed and 

 dried, weighed one grain ; this indicates, in the imperial gallon, 

 3.2 grains of sulphuric acid, equivalent to 5.8 sulphate of soda, 

 dry, or 13 grains crystalHzed. 



B. For the muriatic acid ; nitrate of silver, added to six- 

 teen ounces of the water boiled, and the alkali previously satu- 

 rated, gave a precipitate weighing 2.8 grains ; reduced to the 

 proportion in the imperial gallon, this amounts to 26.9 grains 

 chloride of silver, equivalent to 11 grains chloride of sodium 

 (muriate of soda. ) 



C. The crystalline pellicle separated from a pint of sixteen 

 ounces, on boiling, weighed 0.2 grains. 



This was carbonate of lime ; but in the water the lime would 

 be combined with muriatic acid, forming 0.22 ; or, in the impe- 

 rial gallon, 2.1 dry chloride, or 3.75 crystallized muriate of 

 hme. 



D. The precipitate formed on boiling with muriate of lime, 

 weighed from the pint, 3.6 grains ; from the imperial gallon, 34.6 

 grains ; showing the water to contain in that quantity a car- 

 bonated alkali equivalent to 53 grains of dry, or 59.5 crystal- 

 lized bi-carbonate of soda. 



E. Muriate of barytes, added to the water left on evapo- 

 rating sixteen ounces to two, gave a precipitate weighing 8.2 

 grains ; deducting one grain for sulphate of barytes, as found 

 in experiment A, we have 7.2 carbonate of barytes ; this indi- 

 cates in the gallon 53 grains of dry, and 59.5 of crystallized 

 carbonate of soda, as in the last experiment. 



Lastly, a pint of sixteen ounces of the water, evaporated to 

 dryness, furnished in three trials of saline residuum, weighed 

 after short exposure to a. dull red heat, six grains, or 57.6 from
