The axis of this disturbance is well shown in the town of Low 
Harrogate, by the quarries which have been opened for roadstone 
on either side of the " Bogs " — here the impure limestone of the 
Yoredale series may be seen dipping respectively N.W. and S.E. at 
high angles, on either side of this Kttle valley ; the same thing occurs 
near Beckwith Shaw to the S.W. of Harrogate. From these two 
positions the general run of the axis of disturbances may be easily 
gathered. 
The exact base of the Millstone Grit is not so easily traceable 
in all cases, and can only be followed by very close inspection and 
consideration of the country. On the southern side of the anticlinal 
its general course is from the south of Pannal Ash, across the Stray 
to High Harrogate; to the north of the town its outcrop being 
obscured by faults is not so well marked, the junction with the 
underlying Yoredale measm^es ranging along a N.E, line from near 
Shaw Green, to the north of Harlow Hill and Low Harrogate. 
Between these two lines is an area of about three square miles of 
Yoredale Measures, upon which the town of Low Harrogate is 
situated. 
The highest point of this area is Harlow Hill, 600 feet above the 
sea, and it is here that the greatest amount of disturbances appears 
to have taken place. The sandstone which caps this hill is one of 
the lowest beds of the district, and as we have already seen before, 
underlies the roadstone of Harrogate and Beckwith Shaw, towards 
both of which places it has a considerable dip. About half-a-mile on 
either side of this hill occur some of the principal Sulpher Springs of 
the neighbourhood ; to the more particular discussion of which we 
will now turn ; and glance at their principal chemical constituents. 
I do not propose in this paper to enter into their medical 
qualities — as this has been already ably discussed by several eminent 
medical men — my object is to show the principal constituents of the 
various groups into which the waters may be divided, and to point 
out how one group differs from another. In the tables I have noted 
the characteristic constituents of the principal springs, and it is with 
these only we need trouble ourselves ; the other constituents of the 
water occur only in small quantities, they are probably due to
