ANALYSES OF WELL, SPRING, MINERAL AND ARTESIAN WATERS. 49 
Remarks.—Water turbid, with a large amount of organic 
matter in suspension. Water heavily charged with sulphuretted 
hydrogen. The total solids were found to consist of carbonates 
of lime and magnesia, silica, alumina, sulphate of lime, sulphate 
of magnesia, chloride of sodium, and a large amount of organic 
matter, &c. The free and albuminoid: ammonia, taken with the 
other constituents present in excessive quantities, renders the 
water totally unfit for human consumption, and it may be classed 
as a dangerous water.

Remarks.—Water turbid, with traces of suspended matter 
(clay). This water may be classed as a second class potable water. 
As regards organic impurities 1¢ is just a trifle above the Sydney 
water obtained from the Botany supply, and is a fair description 
of water considering the period of drought we have experienced.
