154 Account of the New Mineral Spring at Albany. 



fervescence. As it was evident that the iron which was sus- 

 pended by the carbonic acid, in one pint of the water, was 

 now held in solution by the marine acid, I made use of suc- 

 cinate of ammonia, as the most successful method of collect- 

 ing it, separately, preferring this to ammonia, which precipi- 

 tates magnesia also. By proceeding in this manner, a brown 

 precipitate was thrown down, which consisted of succinate 

 of iron, and by calcining this in a dull red heat, I obtained one 

 grain of oxyd of iron. The solution in marine acid, being 

 thus deprived of the whole of the iron, there remained 5\ 

 grains of carbonates of lime or magneisa. To separate them, 

 I gradually poured on a few drops of pure ammonia, till the 

 whole of the magnesia was thrown down, which when col- 

 lected and dried, I found amounted to only 1 \ grains ; the 

 remainder, by examination with oxalate of ammonia, proved 

 to be carbonat of lime. From these experiments therefore, 

 it appears, that the residuum which resisted the action of al- 

 kohol and was insoluble in distilled water, consisted of 



Carbonat of Lime, ... 4 grains, 

 Carbonat of Magnesia, - - 1 ^ 



Carbonat of Iron, 1 



We have now only the aqueous solution to examine ; this, 

 which consisted of 64 grains, after the earths had been 

 thrown down, and the whole residuum had been submitted 

 to the action of alkohol, I proceeded to evaporate slowly 

 in a glass vessel ; as the process went on beautiful cubic 

 crystals appeared ; it was then evaporated to dryness, when 

 64 grains of a saline substance was obtained, which was ex- 

 amined in the following manner : 



Experiment 1. On a part of it a few drops of sulphuric 

 acid were poured, and heat being applied, fumes instantly 

 arose, which had the peculiar smell and other properties of 

 muriatic acid. 



Exp. 2. A small quantity of this salt was again dissolved 

 in a wine glass of distilled water, and to this were added a few 

 drops of nitrat of silver, when an immediate dense white pre- 

 cipitate was thrown down. 



Exp. 3. A little of this salt was dissolved in another glass 

 of water, when a few drops of muriat of barytes were poured 

 in, without producing any change. 



Exp. 4. To a small quantity of this saline solution, a few
