1854.] Notes on the Topography of Murree. 467 



same time found considerable quantities in a less perfectly crys- 

 tallized condition, and of an impure nature, but evincing marks of 

 deposition from igneous solution in the alternating layers of the 

 ashy-like calcareous matter, with intervening streaks of dark clayey 

 substance, which the fractured surface of a specimen presents. 



My opportunities for observation having been very limited, it was 

 not in my power to extend my investigations beyond the immediate 

 vicinity of the station ; but two points of considerable importance 

 have come to my knowledge with regard to the geology of this range 

 of hills, — namely, that a thermal spring exists within some twelve 

 or fifteen miles of Murree from which it is worthy of inquiry whe- 

 ther any calcareous deposits now take place, — the other point is that 

 a fossil bone of a large animal, supposed to be of one of the gigantic 

 Pachydermata of the later Tertiary period has been discovered at 

 about a corresponding distance in an opposite direction. 



Meteorology. — No extended observations have as yet been made 

 regarding the meteorology of Murree, as the sanatarium has so lately 

 been established there. It is hoped however that the register taken 

 from the daily observations made at the hospital there for the five 

 months from May to September 1852 inclusive, will, if compared 

 with similar observations made during the same period at "Wuzzeera- 

 bad, show the contrast between the temperature at that place, and 

 in the plains of upper India, while a similar register being inserted 

 of the range of the thermometer in the united kingdom will, it is 

 hoped, render the comparison still more extended and complete. 

 The latter however must refer to Dublin in 1844, as no observations 

 for any other place or time are at present available,
