Surv., vol. II, 1886, p 12 T), showing the water to contain the fol- 

 lowing : 



Potassa trace Ferrous oxide trace 



Soda fairly large quantity Sulphuric acid very large quantity 



Lithia trace Phosphoric acid trace 



Strontia small quantity Silica . " 



Lime .very large quantity Chlorine very large quantity 



Magnesia large quantity 



The -water at iS'S'^ C h.id a specific gravity of 10-0269, ^^^d con- 

 tained 2-925 parts of dissolved saline matter in 1000 of water. 



Sandwich, Essex Co. — At this place is located a sulphurous spring, 



near which was erected an hotel and baths ; owing, however, to the loss 

 of the hotel and bathhouses by fire, the spring has of late years fallen 

 into disrepute. The water is highly sulphurous and flows from an arte- 

 sian boring made some years ago for oil. 



The analysis, according to Prof S. P. Duffield, gave the following 

 result : 



Chloride sodium 0-070 Carbonate lime 4-813 



" calcium 0-007 " magnesia I -618 



" magnesium 19-220 Silica 0-014 



Sulphate lime '5 '479 



Carbonate soda 6-070 Grains in one pint 47 '291 



" potassa traces 



GASES. 



Carbonic acid, cubic inches i '25 



Sulphuretted hydrogen, cubic inches 472 



Nitrogen, cubic inches 0.09 



As may be seen on reference to the above, the waters of this well 

 contain a considerable proportion of chloride of magnesium and 

 sulphuretted hydrogen. 



St. Catharines, Lincoln Co. (a) — Some years previous to 1863 an 

 attempt was made to obtain brine, for the manufacture of salt, at St. 

 Catharines. With this object, a well was drilled in the town to a depth 

 of about 5cofeet, the drill penetrating the Hudson River shales to a 

 distance of 50 to 60 feet. 



A brine of low saturation was obtained but owing to the contained 

 lime and magnesia salts was never used in the making of salt. 



This water was analysed by Prof. Croft of Toronto as given below I. 



In 1 86 1 a second boring was made by Mr. E. S. Adams resulting 

 in the discovery of a water of similar character. Analysis II.
