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 ioth 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 impreffion, 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 flowly green. 

 A watery tincture 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 lpirit of vitriol mixed fmoothly, and oc- 

 cafioned no white cloud, nor more emotion or cloud 

 than if it had been dropt into diftilled water, only 

 fbon after a number of air bubbles collected at the 

 bottom and fides of the glafs j and the fame thing 

 happened, when fbme drops of the ftrong oil of vi- 

 triol were mixed with another parcel. of the water. 



Each drop of a folutibn of pure cryftallifed na- 

 tive foffil alkali occafioned a white cloud, and a 

 white precipitate fell to the bottom of the glafs j but 

 each drop of a folution of fait of tartar cauied a dark 



brown
