Remarks.—The soluble saline matter consists largely of chlorides 
of sodium and magnesium, sulphate of lime, sulphates of soda and 
potash ; the insoluble, of clay, silica, carbonates of lime and mag- 
nesia, etc. Had a very foul odour due to sulphuretted hydrogen 
gas. The use of this water was stated to cause sickness among 
the cattle though the symptoms given rise to were not stated, but 
were probably due to the large excess of the magnesia salts present 
({Epsom’s salts) which tend to act as a purgative. The water is 
unfit for stock purposes, human consumption, and for irrigation. 
The quantity sent (about } litre) was much too small for a more 
complete examination.
