foul odour, and the residue on ignition considerably darkened, 
and gave offa fetid smell. The insoluble matter consisted chiefly 
of clay, carbonates of limes and magnesia, silica, etc.,and the soluble 
of chlorides of sodium and magnesium, with traces of sulphates 
of lime, alkaline nitrates and nitrites. No poisonous metals 
detected. The sample received for analysis being small, a more 
detailed analysis could not be attempted, but sufficient had been 
done to show that the water was totally unfit for human consump- 
tion.
