The following analysis was published by Prof. Doug-lass 

 April 16th, 1860, said to have been performed upon water from 

 the salt well of "Mr. Waldron, of Saginaw," but according to 

 Mr. Waldron, of East Saginaw, taken from the well of the 

 above company: 



Specific gravity, 1 . 110 



Saline matter 22 . 017 per cent- 



Chlorid of sodium, (sali,) 17.912 " 



Sulphate of lime, (gypsum,) 116 " 



Chlorid of lime, [O. of calcium?] 2.142 " 



Chlorid of magnesia, [0. of magnesium ?J ... . 1.5S2 " 



Carbonate of iron 105 " 



Chlorid of potassium, 220 " 



Water, 77 . 9«3 



100.000 



, The chlorid of calcium given here is four times the amount- 

 found by Dr. Webb. 



In May, 1860, another and more accurate analysis of this 

 brine was made by Dr. Chilton, with the following results: 

 Specific gravity at 60° Fahrenheit 1 . 177 



In 100 parts of brine, Salometer 90°, are found, 



Chlorid of sodium 16.8710 



"calcium 3.2h73 



" " magnesium, 1 . 7743 



Bromid of sodium, 0401 



Sulphate of lime, 0982 



Carbonate of lime, 0500- 



Silica and alumina 0245 



Carbonate of iron, 0116-
