Harrogate, about thirty miles west of York, is situated part on high level ground, about six hundred feet above the sea, and part in a sheltered valley. It is surrounded by open and pleasant country, and has a pure and bracing though rather moist air; the sandy soil soon dries after rain. The old sulphur well and the strong Montpelier sulphur well are said to contain 25 cub. in. of sulphuretted hydrogen in a gallon of water, with alkaline and earthy chlorides and sulphides, and traces of bromide and iodide.

They are alterative, stimulant, diuretic, and aperient, and are taken in doses of from one to three tumblerfuls, at intervals before breakfast.

Milder sulphurous springs at the Victoria and Montpelier Gardens are also in use. They contain carbonate of magnesia, and are "antacid, alterative, diuretic, and deobstruent." Both these waters are naturally cold, but are commonly taken warm; they are used also for bathing, the arrangements for which are very good. There are also saline chalybeate and pure chalybeate waters. The social resources of Harrogate and the pleasant climate of summer and autumn (June till October) attract many classes of invalids, but the most suitable cases for treatment by the waters are - dyspepsia with inactivity of liver and bowels, especially when due to high living; constipation, obesity, swelling of joints and glands, chronic skin diseases, gout and rheumatism, syphilis, etc.; cases of incipient phthisis and disordered menstruation in young women are also sent here with advantage, and make use of the warm sulphur baths while taking the chalybeate internally.

Moffat, in the upper part of Annandale, is four hundred feet above the sea, with a good climate and picturesque surroundings. The water, which is cold, contains 2 1/2 cub. in. sulphuretted hydrogen in the pint with 22 gr. of chloride, and 2 gr. of sulphate of soda. It is used internally in much the same cases as the Harrogate sulphur water.

Strathpeffer, in a beautiful part of Ross-shire, has several cold sulphur springs, containing a good proportion of the gas with alkaline and earthy sulphates and 16 gr. of lime salts; these latter render the water somewhat difficult of digestion, and constipating.

At Llandrindrod, in Radnorshire, there are sulphur wells of some reputation, described by Macpherson as "mild Harrogate waters." At Builth (the next railway station) there is a weak sulphur well, and a saline with 66 gr. of chloride; and at Llanwityd there is a weak saline spring with a large proportion (0.62) of sulphuretted hydrogen. The climate at these places is pure and bracing.

The principal sulphur wells in Ireland are at Lisdoonvarna, situated in a bare country, about twenty miles from Ennis (county Clare). They are said to contain 1/2 cub. in. of sulphuretted hydrogen, and are much used, but the accommodation is insufficient. There are also chalybeate springs of good quality.
