470 CLIMATE OF 



The observations made have been principally taken at Subathu and at 

 Kotgerh with some others at intermediate places of encampment daring 

 the march, or a temporary halt; and as the journal in detail may seem too 

 voluminous for publication, 1 beg to offer an abridgement of it. 



The abridgement notes the highest, lowest and mean of each day in 

 every month, inclusive of the observations taken during a temporary halt 

 for the period above-mentioned : and for reference, a list of the places with 

 their heights above the level of the sea, and their latitudes and longitudes 

 will be found at the end.* 



The difficulty at all times experienced of being able to procure proper 

 instruments in India for keeping a correct and regular Meteorological 

 Journal has been a great drawback in the present instance ; and the uncer- 

 tainty of obtaining them from Europe in an efficient state has necessarily 

 confined the observations for the most part to Jhe Thermometer: but con- 

 sidering all things; the peculiar nature of this mountainous, elevated and 

 highly interesting tract of country, and the want of thermo metrical registers 

 in this parallel of latitude, being the first complete set ever offered, it is to 

 be hoped that it may not be found unworthy of attention. 



The observations at Subathu have been limited, with very few excep- 

 tions, to the interior of a house which has an exposed situation, and will 

 give a very good mean, while those at Kotgerh have been taken outside, 

 in the shade, exposed to the wind, so as to shew the true temperature of 

 the atmosphere. After procuring and putting up a Barometer at the latter 

 place, observations of the Thermometer were taken inside as well as out, 

 marked "Attached and Detached" in the column. The Barometer used 

 was unexceptionable in every respect, being a good tube filled with mer- 

 cury, accurately boiled over a slow charcoal fire, and after extracting by

 the Ceded Provinces for the latitudes, longitudes, and heights, of the diUerent places above alluded to.
