DAVIS : MINEEAL WEALTH OF HAEEOGATE. 
uents are brought together, I now furnish a case where an unexpected 
deposit occurs in one of the mineral waters. 
The Alexandra Chalybeate water which springs in the Bog- 
Field, is brought down to the Royal Pump Room in ebonite pipes of 
half-inch bore ; in the course of two or three years the pipe becomes 
completely blocked up by a crystalline deposit, which on examination 
I find to consist principally of lime sulphate, with small quantities of 
lime carbonate and ferric oxide. An analysis I made of this water 
in the summer of 1870, exhibits the presence of a little over 9 grains 
of lime sulphate in the gallon. I am not aware of the conditions 
which cause the deposition, the water springs freely at the rate of 
something like 600 gallons in the 24 hours, it runs without intermission 
through the pipe, which is of narrow bore, and consequently with 
considerable rapidity, such a small quantity of lime sulphate would 
naturally be expected to remain in solution. 
In conclusion, these few remarks are mere indications of the 
Mineral Wealth of Harrogate, the Spas may be regarded as a mine 
only partially explored. There is work enough for the geologist 
and chemist for many years to come, such questions as, how do the 
waters acquire their sulphur constituents, and are they always 
present in the same combination ; is the formation of chloride of iron 
an original constituent like sodium chloride, or produced by some 
process of decomposition ; and other problems might be mentioned 
which await solution. 
ANALYSIS OF THE KISSENGEN SALINE CHALYBEATE WATEE, 
1883, AS COMPAEED WITH ANALYSES IN 1845, 1854, 1867, 
AND 1879. BY E. LLOYD WHITELEY, ESQ., STUDENT IN 
THE YOKKSHIEE COLLEGE. 
In the paper which I have the honour to read before this Society 
there is httle to relate which is interesting, except in so far as it 
may throw a little more light on the character and composition of 
the well-known Kissengen Spring, at Harrogate.
