66 A SURVEY OF THE 
peed with very little alteration. Though, Lam aware, that such minute 
descriptions of localities must appear tedious, and that many repetitions 
occur, I wee they will be excused by those,, who feeling interested in the 
subject, may have the patience to read the detail. To give general 
descriptions of such rude regions is difficult, if not impossible, and I trust 
that particular ones, though often tedious, will be found more faithful, 
and to give more precise ideas, of those remote recesses of the Himalaya, 
which I visited. For this end, and that those who are so inclined, may 
be able to know the positions of the ae in my journey, I have put 
down the bearings, and distances in paces, of each portion of the Route; 
with the remarks noted at the time and also the latitudes of the halting 
places, and these sispple data will enable any. one to trace the distance 
and direction from Reital to. the end of my journey. © have only put 
dow the bearings in single degrees 5 ey are reckoned from Nort, 
which IT call 360: thus, 180 is South, 270 West, and so on—except in 
very steep ascents and descents,, the paces may be taken at 30 inches. 
Own the 19th May, I was joined at Reval by Lieutenant Hernenr, of 
the Sth Rept. N. L who had been appointed my assistant, and from his 
‘skill; and zeal the survey has received much benefit, —Mr. Hersert | came 
‘direct from Caleutta and brought for me a pair of Mountain Barometers, 
but the tubes filled in England had been broken ere they arrived in 
Calcutia: there were some spare emply ‘tabes which’ we filled and used 
as hereafter mentioned, but we could not succeed in eiliie the mercury 
: in the tubes, to free it entirely of air —The height of Reital above the 
sea as indicated by our barometers.is 7108 feet.
