SUBATHU AND KOTGERH. 471 



this tedious, troublesome, and not unfrequently vexatious process (but not 

 without breaking some tubes before succeeding) all the air bubbles and filth, 

 was inverted into a cup of mercury to which was affixed a scale graduated 

 into inches, tenths and hundredths parts. It may therefore be depended 

 upon, and great care was observed, at the time of taking the observations, 

 whether of the Barometer or Thermometers. 



It is necessary to state that the mean of observations taken at intervening 

 places where a temporary halt was made, has been deduced from the highest 

 during the day, and the lowest the following morning, being the only mode 

 left for ascertaining a correct mean of the place for the day. 



Subathu is a small fort and military post occupied by the 1st Nasiri or

 the Himalaya or snowy chain about 65 miles the nearest point ; from the 

 River Setlej or Satrudra 24, and from Kotgerh 40. 



It is a sort of flat or table land having mountains in the neighbourhood 

 in height from 4600 to 8000 feet above the sea. It is open and exposed, be- 

 ing low and near the plains, and in some degree is liable to the effects of 

 the hot winds which blow from the plains during April, May, and June, al- 

 though the intermediate ranges are considerably more elevated. It is on 

 the right bank of a branch of the small river Gambhir which lies to the
