be communicated to the Buxton water, when fre(h 

 ■drawn from the fpring ; a quality, which in many 

 cafes would add greatly to its medicinal efficacy, I 

 fuggefted the trial to Mr. Buxton, a very worthy and 

 fenfible apothecary near the wells, who has lately 

 at my reqUeft made the following experiment. 



Experiment IV. 



A quart bottle containing two drachms of iron 

 filings, was filled by immerfion, with the water of 

 Saint Anne's well, corked and agitated brifkly under 

 the furface of the water : it was then fuffered to re- 

 main in the well till the filings had fubfided, when 

 the water was carefully decanted into a half pint glafs y 

 to this were added three drops of the tinctureof galls, 

 which immediately occafioned a deep purple colour, 

 and tranfparency was prefently reftored by a few drops 

 of the acid of vitriol ; evident proofs that a folution of 

 the iron was effected in a few minutes. The water 

 ahb without the tincture of galls had a chalybeate tafte, 

 and left an agreeable aftringency on the palate. 



By this experiment, it appears that a warm chaly- 

 beate abounding with a mineral fpirit, and grateful 

 to the tafte, may with very little trouble be obtained.. 

 And this method of impregnating the Buxton water 

 with iron, mud increafe its tonic powers, and in 

 many cafes improve its medicinal virtues. It is a 

 common practice to join the ufe of a chalybeate 

 fpring in the neighbourhood of St. Anne's well,, 

 with that of the Buxton water : but, the fuperiority 

 of the artificial mineral water muft be apparent, if 

 we confider its agreeable warmth, volatility, levity, 

 and gratefulnefs to the palate.
