11 The springs are not regular in the quantity of water which they 

 discharge. On the 27th of October last, I estimated that the Soroo 

 Noon-poong was discharging about 30 gallons of water per minute. 

 The waters of the Burra Noon-poong being mingled with those of the 

 jan, renders it difficult to form any just estimate of the quantity of 

 water discharged in a given time ; this circumstance also accounts for 

 the low temperature of the spring." 



The memoranda are dated, Golaghat, November 1st, 1854. 



The chemical examination by Dr. Warden yielded the following 

 information : — 



parts per 100,000 



Total solids at 100° C 124 



Chlorine 66 ! ! 



The water was too old for estimation of organic matter. Nitrates 

 and sulphates were present : nitrites absent. There was a distinct 

 trace of H 2 S, but whether this was originally present in the water or 

 produced by the action of sulphates in the presence of organic matter 

 the analyst was not in a position to offer an opinion. There was black- 

 ening of the solid residue left after evaporation of the water — on 

 ignition — indicating presence of much organic matter.
