So far Dr. Mackenzy. From others I have been 
informed, that this water has been ufed with fuccefs. 
in many of thofe cutaneous diforders commonly called 
fcorbutic, and in curing the itch. 
In order to difcover the particular contents of this 
water, I began to examine the bottles, which had 
been fent me, on Tuefday, the 10th of September, 
which was about five weeks after the water had been 
taken up from the well. The bottles were all well 
corked, and the tops of the bottles had been dipt 
into melted wax fo foon as they had been corked. 
The water was as clear and limpid as the pureft rock 
water. It had ftill a very ftrong fulphureous fmell 
and tafte ; but it had no other but a fulphureous tafte, 
and it made no imprefflon, on the tongue, of fea or 
any other fait. 
Some of it was poured into different glaffes and tea- 
cups, and different things put into each. 
Syrup of violets became ftowly green. 
A watery tin&ure of galls occafioned no particular 
change of colour, but brought a variegated fcum, of 
the colour of a pigeon’s breaft, to the furface. 
A diluted fpirit of vitriol mixed fmoothly, and oc- 
cafioned no white cloud, nor more emotion or cloud 
than if it had been aropt into diftilled water, only 
foon after a number of air bubbles collected at the 
bottom and fides of the glafs ; and the fame thing 
happened, when fome drops of the ftrong oil ol vi- 
triol were mixed with another parcel of the water. 
Each drop of a folution of pure cryftallifed na- 
tive foffil alkali occafioned a white cloud,, and a 
white precipitate fell to the bottom of the glafs ; but 
sach drop of a folution of fait of tartar caufed a dark 
brown
