This water (I) acquired quite a reputation locally and was partly 

 evaporated and shipped in a concentrated state. Of this concentrated 

 water, the following analysis, made by J. R. Chilton, M.D. 1853, is 

 given in "The mineral springs of the United States and Canada, by 

 Geo. E. Walton, M.D. New York 1874"

"The large amount of proto-chloride of iron was probably formed 

 from the surface of the iron vessel during evaporation." 



"These celebrated waters are the most perfect type of iodo-brom- 



ated water known in this country. They very much resemble the 



celebrated waters of Krueznach, in Prussia, though containing the 



chloride of sodium, calcium and magnesium in much larger proportions."

Silver Islet, Lake Superior. — The following analysis was made by 

 Mr G. C. Hoffmann (report Geological Survey Vol. I, 1885, p. 17 M) 

 of a specimen of water collected at the Silver Islet mine by Capt. 

 Trethewey in 1882.
