Sulphureted hydrogen gas, Sulph. lime, 



Carbonic acid gas, Oxide of iron, 



Chloride of magnesium, Carbonate of lime, 



" sodium, Sulphuret of calcium, 



" calcium, Iodine, 



Sulph. magnesia, Traces of organic matter. 

 Temperature, 52° Fah. 



A chalybeate spring on the same grounds shows, according to Prof. 

 E. S. Payne— 



Sulph. iron, Iodine, 



Oxide of iron, Carb. lime, 



Carb. acid gas, Potassa, 



Sulph. of magnesia, Sulph. lime, 



Chloride of calcium, Traces of organic matter. 



Temperature, 56° Fah. 



A so-called magnesian spring on the same grounds shows, by the same 

 authority — 



Sulph. magnesia, Carb. of lime, 



Chloride calcium, Iodine (small), 



Oxide of iron, Potassa (small), 



Sulph. of lime, Traces of organic matter, 



Earthy phosphates, 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, Carbonate of lime, 



" magnesia, Traces of potassa, 



Chloride of calcium, Traces of organic matter. 



Oxide of iron, 



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. J section 4, Kingston, Mr.
