It is well known that there are a number of springs at Saratoga, the waters of which bear 
a general resemblance to each other. But owing either to some difference in the chemical 
composition, or to the influence of fashion, some particular spring has always been more cele¬ 
brated than all the rest. Such is at present the case with the Congress spring, and the che¬ 
mical composition of its waters will unfold to us that of several others found in its immediate 
vicinity.
