spring at Spadina, remarkable for the quantity of lime de- 

 posited. There is also a spring in the village of Brompton 

 " regarded as mineral, with smoky taste ; the waters of 

 which become putrid and sulphureous in closed bottles. " 



Another at Brompton contains a small quantity of chlo- 

 ride and sulphate of lime, magnesia, and alkalies. Perhaps 

 none of these springs rise from the "Lower Silurian," but 

 "owe their mineral contents to clays and muds, covering the 

 palaeozoic rocks." 



There are also a number more springs enumerated by Dr. 

 Bell and others, in Canada, with analyses proximate and 

 otherwise. The following are the most conspicuous and 

 important noticed by writers on the subject. 



TUSCARORA ACID SPRINGS. These springs are in the 

 Township of Tuscarora, twenty miles south of Pass Dover. 

 They contain, according to Mr. Hunt, the sulphates of iron, 

 lime, magnesia, alumina, and a large amount of free sul- 

 phuric acid. It is asserted by geologists that " this spring 

 is in the same geological relationship in which the same cha- 

 racter of springs in New York are found." It has also the 

 smell and taste of sulphuretted hydrogen, with an extremely 

 acid and styptic taste. 



There are several smaller basins in the neighborhood with 

 the same character of waters. They all contain sulphates 

 of potash, soda, lime, magnesia, iron, and alumina, and sul- 

 phuric acid in quantities. 



A few miles south of Port Dover, on Lake Erie, is CHAR- 

 LOTTEVILLE SULPHUR SPRING. Temperature, 45 Fahr. 

 The water is clear, with a sulphureous taste and a strong 

 sulphur odor, and contains sulphates of soda, potash, lime, 

 and magnesia, chlorides of magnesium, carbonate of lime, 

 magnesia, and iron, sulphuretted hydrogen, and carbonic 

 acid. The sulphuretted hydrogen is in the quantity of 26 '8 

 cubic inches to the gallon. (Hunt.) 



ANCASTER SPRING is near the village of Ancaster. It is 

 a salt spring, with a temperature of 48 Fahr., the water 

 containing chloride of sodium, chloride of potassium, chlo-
