 is at first, habit not only renders them- tolerable ; but to

most persons very agreeable. Most of the invalids whom I 

 sent to the waters, drank them after a short time with great

avidity, to the amount of several gallons in a day: and some 

 of the most intemperate of them assured me, with great seri- 

 ousness, that they preferred them to any kind of spirits. 



Having thus executed the first part of my plan, I shall 

 next mention the experiments which I made on the waters. 

 These, on account of the distance of the springs from the 

 post where I was stationed, and the want of a proper chemi- 

 cal apparatus, were few and simple. They were sufficient, 

 however, to determine the general impregnation of the wa- 

 ters, though not to ascertain the proportions of the combi- 

 nation in the several wells. 



1st". A quantity of the water was evaporated to dryness 

 by boiling; a greyish insipid powder remained, which pro- 

 duced a strong effervescen'fce with the vitriolick acid, and ap-

2d. To some of the water I added a 'small proportion of 

 the vitriolick acid ; this occasioned a violent effervescence for ^ 



a 



time: after it had subsided, the water lost 



al milky hue, and became as transparent as common water ; 

 its acidity wa*s increased; but not in proportion to the 

 quantity of acid that had been added. 



3d. I threw into the w^ater a quantity of salt of tartar, 

 which instantly dissolved without producing the least effer- 

 vescence. The water, however, became immediately turbid 

 and milkv. On standinof a few minutes, the milky sub-
