356 OLIVEE : MINERAL SPRINGS OF THE WEST RIDING. 
The foreg-oing" notes appear to me to support the following" 
conclusions : — 
1. The saline and sulphur waters of the anticlinals of the West 
Riding", issue in proximity to the lines of Elevation. 
2. The large proportion of Chlorine Salts present in the Harrogate 
saline waters, whether sulphuretted or ferruginous, is of 
marine origin and is probably derived from the ancient sea 
in which some of the carboniferous rocks were laid down. 
3. The theory of the reduction of sulphates by means of vegetable 
or animal organic matter, frequently, if not generally, held by 
geologists as applicable to all sulphur waters, cannot be 
entertained as the explanation of the sulphuration of the 
Harrogate waters : chemical evidence being opposed to its 
adoption. 
4. A soluble salt of Barium exists in relatively larg"e quantity in 
the sulphate-free waters of Harrogate : and is probably 
derived from Witherite, which has been found in associ- 
ation with metallic sulphides in the lower carboniferous 
rocks. 
5. The Harrogate saline waters are all derived from a common 
source : the differences in composition — even those observ- 
ed within very narrow limits — being accounted for by the 
separate channels provided by the shales, which convey 
the waters to the natural issues, or the bore-holes of wells ; 
by chemical re -actions ; by the disposition which solutions 
of salt have to arrange themselves in certain levels, accord- 
ing to concentration; and by the varying amounts of 
supply- water which reach the various outflows. 
6. The chemical history of the Chloride of Iron Well, is an inter- 
esting illustration as to the important part played by 
chemical re-action in the production of a mineral water, 
which — in the case of an artifical outlet provided by a 
well — may only acquire a settled composition after the 
lapse of many years.
