908 AN ACCOUNT OF THE 
perty, made by Bar‘aup, and had three very fine ones, my private property,. 
made by Brocksanxs and Mouineux. ‘The list of longitudes annexed is 
important, as the first meridian is settled from twenty-four immersions and 
emersions of the first satelite, being a much greater number of observations 
than have I believe ever been taken m the upper provinces, to fix so. interest=. 
ing a point. It was known to the late Surveyor General, Colonel Cousz-- 
BROOKE several years ago, as well as to myself, that the longitudes assigned’ 
to Haridwar and several places in Rehiiehand, by Mr. Revzen Burrowss,, 
were too far to the west by about seven miles. The name of Burrowss 
deservedly stands high, asa learned mathematician, as well as anexpert astros. 
nomer, but it is many years since he took his observations in Rohilc hand, and 
at that time the astronomical tables were less perfect than.at present, and Mr. 
Burrowes used a telescope of small power, and I believe took a very small 
number of observations:of the satellites in comparison with ours. I do not 
presume to disparage the operations of so distinguished an astronomer, so far 
as his means of accuracy admitted, but it is well known that the due obser- 
vation. of the eclipses of the satellites, and thence determining differences of 
longitude, is by no means difficult to any person: moderately skilled in: practic 
cal astronomy, so that those who have the best modern instruments and 
tables, and can take the greatest number of good sights, can’ give the. most 
accurate results. 
Tue pyramid which I built at the trigonometrical station on. the Chiy in 
1816, is the first meridian :-— 
Its longitude being 77. 28. 30. 
Its latitude 30. 50. 36.
