dences of the change wrought by it, are found abundantly scattered 
through our State. The theory which has been suggested as applicable 
to the particular locality above described, requires a more full examina- 
tion than the present occasion would warrant, and I shall therefore leave 
for another opportunity its further elucidation. 
This is the most complete account which I can at present give of the 
mineral springs of the State of New- York. Although their number is 
already large, there is no doubt that it will be greatly increased before 
the completion of the Survey now in progress. It will be observed, that 
even of those now known, only a small proportion have been examined 
with that care which is necessary, in order to determine their chemical 
composition. Whether the investigations and analysis thus commenced, 
shall extend to all the more important springs of the State, must be de- 
termined by those under whose authority this department has been in- 
stituted. 
In my next annual communication I hope to present an account of 
the minerals found in this State, (other than those noticed in my former 
report) which are used in the arts. 
I have the honor to be. 
Your obedient servant, 
LEWIS C. BECK.
