ALUMINOUS CHALYBEATE SPRING IN I. OF WIGHT. 53 



soon perceived by a few preliminary experiments, that its 

 principal ingredients were sulphate of ir6n and sulphate of 

 alu-miue, a;,d that it possessed a degree of strength far more 

 considerable than any mineral water of the same kmd that 

 ever came to my knowledge. 



This last circumstance, and the probability that this 

 spring might some day attract public notice from its medi- 

 cinal properties, induced me to undertake the present 

 analysis, which, after many interruptions, I have at length 

 brought to a conclusion. 



Sect. I. Situation and Natural History of the Spring, 



This spring is situate on the south-west coast of the Isle Situation and 



of Wight, about two miles to the westward of Niton*, m ""J"* 1 h "'. st0r y

one of those romantic spots for which that coast is so re- 

 markable. 



In its present state it may be said to be of difficult access, 

 for there is no carriage road, nor even any regular foot path 

 along the cliff leading to it, and the walk would appear 

 somewhat arduous to those unaccustomed to pedestrian ex- 

 cursions. But it would be practicable, and probably not 

 very expensive, to render this path equally easy and agree- 

 able. It *.vas in walking along the shore, a few years ago, 

 that Mr. Waterworth's attention was accidentally directed 

 to this spring, which he traced to its present source, by 

 observing black stains formed by rivulets flowing from that 

 spot. 



With regard to the mineralogical history of that district, Mineralogy of 

 I have been favoured through the kindness of my friend the district. 

 Dr. Berger, who visited tl?e spot very lately, with so much 

 more accurate an account of it than 1 should, from my 

 own observation, have been able to offer, that I shall make 

 no apology for transcribing it in his own words. 



" The aluminous chalybeate spring", says Dr. Berger, 

 " issues from the clitfon the S. S. W. coast of the Isle of 

 *' Wight, below St. Catharine's seamark, in the parish 

 «* of Chale. The bearing of the Needles from the spot is
