Measure area of this State. The water of the well is. of course, largely charged 

 with mineral matters, a portion of which being held in solution bj' the free car- 

 bonic acid with which the water abounds, is deposited as a thick sediment upon 

 allowing the water to stand for some time freely exposed to the open air. By 

 repeated and careful ex]jeriments, I determined the temperature of the water to be ' 

 uniformly 61° F., as from the great depth from which the water rises it exhibits 

 little or no vai'iation in temperature through summer or winter. A full analysis of 

 the water presents the following results : Specific Gravity, 1.0138. Temperature, 

 61° F. Total Mineral Matter to the Imperial Gallon, 1100.081 grains. Carbonic 

 Acid Gas, 145.881 cub. in.

The results of the above analysis have been in all cases duplicated, and in many 

 cases triplicated. Like the product of all mineral wells, this water of course varies 

 somewhat, within slight limits, in its composition. Thus in the water examined 

 by me there was absolutely no trace whatever of sulphates, whereas I observe that 

 Prof. G. E. Patrick, in his paper read before the Academy last year, reports the 

 presence of a very small quantity of Sodium Sulphate. I notice, however, that 

 Mr. Patrick also reports in his analysis an appreciable quantity of Ferric Chloride 

 (Sesqui-Chloride of Iron). If this salt of iron is indeed present in this water it is 

 a most remarkable fact, as there is no well authenticated analysis showing its exist- 

 ence in any mineral spring in the United States. My own analysis indicates no 

 such condition, the iron being present in the water analyzed by me in its usual form 

 in all mineral waters, viz., held in solution as the Bi-carbonate. For the purpose 

 of comparison I give below a tabular view showing the compositiou of the lola 

 water as contrasted with that of two of the most noted of the Saratoga Springs, 

 the " Congress " and the " United States :"
