258 THE lOLA (KANSAS) MINERAL WELL. 



18 expelled by the elastic force of the gas in very irregular pulsations, at 

 varying intervals escaping alternately first with great impetus and then 

 with a succession of fainter impulses. The sections of the core obtained 

 during the boring present, when arranged in order, a most interesting view 

 of the geological section of this region ; especially instructive as it occurs 

 over the Lower Coal 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 by the free carbonic 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 rejDeated and careful experiments^ 

 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 variation 

 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. Car- 

 bonic Acid Gas, 145.891 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 re- 

 markable 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 analysed by me in 

 its usual form in all mineral waters, viz. held in solution as the Ei-carbon- 

 ate. For the purj)ose of comparison I give below a tabular view showing 

 the composition of the lola water as contrasted with that of two of the
