WEEMS.In the investigation of deep well waters the interest inmany cases has been limited to the mineral substances,and little attention given to the sanitary analysis. This isa natural result when it is realized that these waters contain large amounts of solids and the possibility of contamination by sewage or other products is very slight indeed.In connection with the work of the Department of Agricultural Chemistry of the Agricultural College, analyses ofa number of samples of water from the deep wells of thestate have been made and the results brought together inhope that they may be of interest. The methods used donot require any explanation as they are those which havebeen generally used for analyzing water.
