334 Artificial Preparation of Medicinal Waters. 
Feeling, as many persons do on leaving the springs, a strong incli- 
nation to partake of the water, especially of the Congress spring, in 
a situation where I could not obtain it, I had recourse to the knowl- 
edge I had acquired of its contents from my previous analysis, and 
after performing some experiments on the subject, I succeeded in 
making such an imitation of it, as satisfied me that the preparation 
which I had made possessed all the essential qualities of the spring 
itself, that its taste was even more pungent and agreeable, and that 
when access could not be had to the spring, it may be used, medici- 
nally, with nearly the same advantage. J continued not only to use 
it myself, when necessary, for several seasons, but diftibuted it to 
many of my acquaintance who were so well’satisfied with its perfect 
imitation and the beneficial effects of it, that I was induced to offer it 
to the public in the year 1827. The method which I first pursued 
was to prepare two different powders containing those substances 
with which the mineral water at the spring was impregnated, in the 
proper proportions to make one tumbler of water, constituting an 
effervescing draught, upon the same principles as I have already de- 
scribed. The advantages of this method of making an imitation of 
the waters of any spring extemporaneously when the natural water 
could not be had ina state of purity, will appear obvious; these 
powders are portable and easily prepared, they could be taken in 
any country or climate, and made use of on a journey whenever they, 
were required ; not feeling, hdwever, inclined at the time to com- 
mence the business of preparing them myself, I committed the prep- 
aration of these powders to other persons, from whom I received the 
most flattering accounts of their success; Subsequently, however, I 
was informed that complaints had been made, that in many instances 
they were liable to deliquescence when kept for any time, and © 
course that their medicinal qualities were impaired, and the efferves- 
cence caused by a union of the different substances which constituted 
powder was impaired. 
- Still, not willing to abandon my intention of imitating the Congress 
water effectually, and without the risk attending a deliquescence of 
the materials, I turned my attention again to the subject, and after 
repeated experiments, I succeeded not only in effectually coun- 
teracting any tendency to deliquescence in any climate, but also dis- 
c a method of uniting the whole constituents of the spring 
in one powder, a spoonfull of which was sufficient at any time to 
make one glass of water so perfectly similar in all its properties to the
