On the whole, I would state, that I consider the State of Michigan 

 one of the most favorable for health, of any of those States that lie to 

 the south, south-west, and west of her, and that she compares most fa- 

 vorably with those that are termed the New England States — with New 

 York, New Jersey and Pennsylvania. ' 



Respectfully yours,

REPORT ON THE ANALYSES OF WATERS. 



by professor s. h. douglass. 



Laboratory of the University of Michigan, ) 

 February 11th, 1854. [ 



To the Board of Water Commissioners of the City of Detroit: 



Gentlemen — On the tenth day of November last, I received from 

 J. Houghton, Esq., Superintendent of your City Water Works, three 

 stone-ware jugs, containing water from the following localities, viz : 



No. 1. From the iron pipe at the residence of A. C. McGraw, on Jef- 

 ferson Avenue, between Rivard and Russell streets, collected January 

 25th, 1854. 



No. 2. From the wooden logs at the residence of Dennis Cuyle, cor- 

 ner of Orchard and Fifth streets, Crawford Park, collected October 5th, 

 1853. 



No. 3. From a well at the residence of Amos T. Hall, on Woodward 

 Avenue, Park lot 11, collected October 5th, 1853. 



These waters were accompanied with a request to have them analyzed, 

 and to report the result to you at my earliest convenience, with such 

 suggestions, founded on the analysis, as 1 should conceive important, to 

 be taken into consideration in the construction of the new Water Works. 

 Having completed the analyses, I herewith submit the result. 



Before proceeding to consider the composition of the waters above 

 named, it may not be inappropriate to make a few remarks on the va- 

 rieties of water in common use for domestic purposes ; the impurities of 

 each variety, and the sources of those impurities.
