feet, at which a cavity was struck which let the augur drop two feet. A 
chemical examination of the water from this well is reported by Prof. 
H. S. Payne to show the following mineral substances: 
Sulphureted hydrogen gas,. 
Carbonic acid gas, 
' Chloride of magnesium, 
A sodium, 
. calcium, 
Sulph. magnesia, 
Sulph. lime, 
Oxide of iron, 
Carbonate of lime, 
Sulphuret of calcium, 
Jodine, 
Traces of organic matter. 
Temperature, 52° Fah. 
A chalybeate spring on the same grounds shows, according to Prof. 
EK. S. Payne— 
Sulph. iron, 
Oxide of iron, 
Carb. acid gas, 
Sulph. of magnesia, 
Chloride of calcium, 
Todine, 
Carb. lime, 
Potassa, 
Sulph. lime, 
Traces of organic matter. 
Temperature, 56° Fah. 
A so-called magnesian spring on the same grounds shows, by the same 
authority— 
Sulph. magnesia, 
Chioride calcium, 
Oxide of iron, 
Sulph. of lime, 
Earthy phosphates, 
Carb. of lime, 
Iodine (small), 
Potassa (small), 
Traces of organic matter, 
Carbonic acid gas. 
Temperature, 54° Fah. 
Another spring, near these, was found by Prof. Payne to afford the fol- 
lowing impurities. This is denominated a “saline chalybeate spring’’: 
Sulph. lime, 
‘« magnesia, 
Chloride of calcium, 
Oxide of iron, 
Carbonate of lime, 
Traces of potassa, 
Traces of organic matter. 
Temperature, 55° Fah. 
A sulphur spring occurs also on John Phillips’s farm, one and a half 
miles south-west of Delhi. 
In the survey of the county the following observations made on the 
common wells were recorded. On the N. E. } section 4, Kingston, Mr.
