This large admixture of saline ingredients rendered the boring 
unavailable for the increase of the water-supply; but the boring- 
rods were driven 30 feet further in the hope that possibly this 
mineral water might find some other subterranean means of 
escape. The hope was of course disappointed, and the operation ter- 
minated at a depth of 451 feet from the surface, the lower 348 feet 
of the boring having been found to pass wholly through “ whin- 
stone ” in numerous bands of varying hardness and colour. Two 
samples of the water, taken when the ultimate depth had been 
reached, were submitted for analysis to different chemists, and gave 
nearly similar results. The proportions of salts obtained by Mr 
Robert M‘Alley, Falkirk, were the

One character of the water not noticed in the analyses, but dis- 
tinctly perceptible to me in a freshly drawn sample, was the odour 
of sulphuretted hydrogen. I may add that the bore was begun 
from the bottom of a previously made well 18 feet from the sur- 
face, and that I found the water flowing out abundantly from the 
top of the bore-tube into the well from which it w r as temporarily 
pumped away. 
It was evident that the idea of any subterranean communication
