Of the mineral matter of No. 1 sample a considerable proportion 

 seems likely to be chloride of sodium, owing to the large proportion of 

 chlorine and the very slight hardness of this water. In No. 2 sample, 

 the extreme degree of hardness is accounted for by its traversing a lime 

 formation — it seems to contain an excess of carbonate and also of sulphate 

 of lime. The Sita-kund water appears to contain chloride of calcium 

 and perhaps sodium. The absence of blackening of the solid residue 

 on ignition indicated the absence of organic matter from all of the 

 samples. All contained sulphur in the form of sulphates. 



The gas evolved at the springs has when sensibly odorous or 

 otherwise been noted in column 13 of Table I — very slight traces of 

 sulphuretted hydrogen are detectable by smell. Nitrogen is a gas 

 which is evolved from hot springs in much greater quantity and more 

 frequently than sulphuretted hydrogen,* but samples of the gas evolved 

 could not be collected for analysis : one characteristic of nitrogen is 

 that it does not support combustion ; and in every case the bubbles of 

 ffas from the springs extinguished a light, but the bursting of the bub- 

 ble on the surface would of itself tend to blow out the light. Carbonic 

 acid is occasionally evolved from hot springs — in the last two samples 

 it could not be present in any quantity, judging from the absence of 

 pungency in the taste of these waters : no direct test by lime or other- 

 wise was resorted to: in every case the waters were neutral to test-paper.
