be communicated to the Buxton water, when frefh 
drawn from the fpring ; a quality, which in many 
cafes would add greatly to its medicinal efficacy. I 
fuggefled the trial to Mr. Buxton, a very worthy and 
fenlible 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 j 
to this were added three drops of the tindlureof galls, 
which immediately occafioned a deep purple colour, 
and tranfparency was prefently reflored by a few drops 
of the acid of vitriol ; evident proofs that a folution of 
the iron was effiedfed in a few minutes. The water 
alfo without the tindture of galls had a chalybeate taffe, 
•and left an agreeable affringency on the palate. 
By this experiment, it appears that a warm chaly- 
beate abounding with a mineral fpirit, and grateful 
to the taffe, may with very little trouble be obtained. 
And this method of impregnating the Buxton water 
with iron, muft increafe its tonic powers, and in 
many cafes improve its medicinal virtues. It is a 
common pradtice 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 muff be apparent, if 
we confider its agreeable warmth, volatility, levity, 
and gratefulnefs to the palate.
