tially oxidized, and deposits a yellowish sediment of ferric hy- 
droxid. This water is of entirely different composition from 
the river water, as repeated analyses have shown. Waters of 
this character are common in the bottoms of the Kansas and 
Missouri river valleys, and also in various localities in the 
great Mississippi basin, as has been noticed by several chem- 
ists. The sample drawn from the service-pipes does not show 
the full amount of iron found in the well.
