The first spring is called the Avon New Bath spring, and was dis- 
covered by the present proprietor, in 1835. Its depth is about thirty- 
six feet, and the formation through which the water rises is the calci- 
ferous slate similar to that found at Rochester, The temperature of this 
spring is about 50° F. The specific gravity of the water 1.00356.* 
One pint of water from the Avon New spring contains 
Carbonate of lime, 3.37 grains. 
Sulphate of lime, 0.44 " 
Sulphate of magnesia, 1.01 " 
Sulphate of soda, 4.84 " 
Chloride of sodium, 0.71 " 
10.37 « 
Sulphuretted hydrogen, 3.91 cubic inches. 
The middle spring is situated about thirty rods east of the former. 
Its temperature is 51° F. The following, according to Prof. Hadley, 
is the composition of a pint of this water. 
Carbonate of lime, 1 . 00 grains. 
Sulphate of lime, 10.50 " 
Sulphate of magnesia, 1 . 25 " 
Sulphate of soda, 2.00 " 
Chloride of sodium, 2 . 30 " 
17.05 " 
Sulphuretted hydrogen, 12 . 0 cubic inches. 
Carbonic acid, 5.6 do 
Gaseous contents, 17.6 do 
The third or lower Avon spring is undoubtedly similar in its compo- 
sition to the preceding, but I have not yet had an opportunity of sub- 
jecting it to analysis. It is remarkable for the large volume of water 
which it discharges. This has been estimated to be equal to fifty-four 
gallons in a minute, and I apprehend that this is not far from correct. 
The waters of all the Avon springs give out powerfully the odour of 
sulphuretted hydrogen, and have a strong saline taste. They speedily 
blacken silver and the salts of lead. The solution of arsenious acid is but 
* The water of this spnng, wlien heated, assumes a beautiful green colour, the cause o' 
which I have not yet been able to determine. I intended to have made careful analyses of the 
waters of all these springs, but in consequence of my not receiving the specimens for the pur- 
pose, I am obliged to defer them until the next season.
