THE MINERAL WATERS OF ASKERN IN YORKSHIRE. 
BY C. H. BOTHAMLEY, F.I.C., F.C.S. 
{Read January 16th, 1894.) 
The West Riding of Yorkshire is remarkable in possessing, at 
Harrogate and Askern respectively, two groups of Sulphuretted 
Waters, each of which, in its own way, is unique in the United 
Kingdom. The Harrogate Waters have been somewhat frequently 
examined, but no analyses of the Askern Waters have been made 
since those of Lankester and West in 1840," although since that 
time structural alterations have been made in some of the wells, and 
the reputation of the waters in the treatment of skin diseases and 
chronic rheumatism, has steadily increased. 
It seemed very desirable that these waters should again be care- 
fully examined, and, whilst at the Yorkshire College, I undertook an 
investigation which comprised the estimation of the dissolved consti- 
tuents in each of the waters, and also the determination of the more 
important of them, and especially of the sulphuretted hydrogen, at 
various seasons of the year. The results have been communicated 
to the Chemical Society, but it seemed appropriate that they should 
also be brought before a society which is specially interested in all 
scientific matters relating to the West Riding. 
* I am indebted to Mr. Richard Reynolds, of Leeds, for calling my 
attention to this fact.
