2° 25' hotter than the hottest Spring- of Switzerland. 



Temperature of 3rd and principal Spring which is the saint's shrine, 

 and which feeds the Alligator ponds.

The water of these springs, where it first issues, has a slightly sul- 

 phureous smell and taste, but after a short exposure to the air, becomes 

 perfectly sweet and pure ; it leaves a slight blackish deposit on the 

 pebbles. The rocks in the vicinity are found in ridges nearly concen- 

 tric curves. The strata appear to dip from the centre of the curves 

 at an angle varying from 50° to 80°. They consist of an upper 

 cap of coarse limestone overlaying coarse soft sandstone, below which 

 the strata is hidden by debris. The rocks abound with exuviae of 

 zoophites, echini and pectines, a few coats of small spiral and bivalve 

 shells are met with, but in no abundance, till nearing the Hub or 

 Pub river beyond the basin formed by the curved ridges, small fossil 

 crabs and other fossils similar to the Kurrachee fossils are met with in 

 abundance, but none of the rarer sort that distinguish the Kurrachee 

 bed from all the other formations in Scinde. There are a few other 

 springs in the neighbourhood of these hot springs, but they are cold 



* All three names were given me.
