And the gases, — Sulphuretted hydrogen 2j- 



Carbonic acid 4 



Nitrogen 4;-- 



Carburetted hydrogen 4 Total... 1.5 cubic inches. 



At Bolton by Bolland, on the extreme western verge of the county, in the grounds 

 of Mrs. Littledale, is a weak sulphureous spring : though unprovided with baths, and 

 indeed too small at present to supply them, it has credit in the neighbourhood as a 

 medicinal water, for both internal and external use. 



The water of the Aire and the Wharfe, at their sources near Malham, is strongly 

 petrifying ; large masses of calcareous deposit abound among the cliffs of Gordale 

 Scarr ; Josh. Spence found 12i grains of solid matter per gallon, of which 12 grains 

 was carbonate of lime. 



Huddersfield has in its neighbourhood two sets of baths ; at Lockwood, one mile . 

 south, the water is sulphureous, containing 



Sulphuretted hydrogen 1-836 



Carbonic acid -JoG 



Carburetted hydrogen 3-78 



Nitrogen 4-428 Total... 10- 8 cubic inches. 



The only solid contents are carbonate of lime, 7-8 ; sulphate of magnesia, -8 ; and a 

 trace of chloride of calcium. 



Here we have the compounds of hydrogen with carbon and sulphur, without their 

 usual accompaniments of chlorides or carbonate of soda. 



At Slaithwaite baths the characteristic ingredient is carbonate of soda; the analysis 

 of two springs gave me — 



Chloride of calcium -75 -7 



Chloride of magnesium -4 -4 



Chloride of sodium 2-65 2-5 



Carbonate of soda 17-8 20-4 



Total... 21-6 24- 



From the construction of the pumping apparatus, large bubbles of gases continually 

 escape and may be inflamed by a candle ; these, from their burning with a blue flame 

 and sulphureous smell, are believed in the neighbourhood to be hydrosulphuric acid, 

 " sulphur " as they term it ; they consist, however, of a small quantity of that gas, with 

 much carburetted hydrogen and some nitrogen and carbonic acid. The waters yielded 



Sulphuretted hydrogen •7.5 



Carbonic acid 1-2.5 



Carburetted hydrogen 4-7.5 



Nitrogen 6*25 Total... 13 cubic inches. 



The excellence of a pure sodaic water for steam-engines is well illustrated here ; I 

 was assured that the bottom of the boiler which supplies the pumping-engine and hot 

 water for baths remains "bright like silver;" this I suppose an exaggeration, but 

 that it never requires cleaning is a circumstance more credible and sufiiciently de- 

 sirable. 



At this spot I found, in greater abundance than anywhere else in my experience, 

 that remarkable substance, the organic composition and equivocal nature of which 

 has exercised the ingenuity of chemists. 



Not far from the baths is a chalybeate spring, yielding — 



Sulphate of soda 1-7 



Carbonate of lime 3- 



Carbonate of magnesia 2-1 



Protoxide of iron 1-8 Total... 8-6. 



I had an opportunity of examining the ordinary waters of the neighbourhood of 

 Huddersfield on the north side, from analysing many springs about Honley; they gave 

 from 2 to 12 grains of solid matter, generally about 8, of which about half consisted 

 of salts of lime.
