410 Mr. Goldingham on the geographical situation of 
servations taken at different places in India ; the differences 
of meridians between which and the Observatory are cor- 
rectly known, either from correspondent eclipses, chrono- 
meters, or by survey. These having been taken with different 
telescopes, and by different observers, and also at a distance 
from the Observatory, may be considered as less valuable 
than those observed there, with the same description of tele- 
scope, and under every favourable circumstance. 
The second result is from eclipses taken at Madras, with 
different telescopes, at two or three different points, and re- 
duced to the Observatory. These may also be considered 
of less value than the third result, which is drawn from 
eclipses taken at the Observatory with the same description 
of telescope, and under favourable circumstances. I have, 
therefore, in drawing the conclusion, considered a mean of 
the first and second results as about equal in value to the 
third, and have combined them accordingly. The fourth 
result is from correspondent eclipses, which I considered of 
equal value with the other three results. This relates to the 
first series of eclipses from 1787 to j8oi. 
In the second series, containing eclipses taken between the 
years 1803 and 1816, the first result was deduced from ob- 
servations taken at the Observatory with the same descrip- 
tion of telescope, and is therefore of equal value with the 
mean of the two first results, and also with the third of the 
other series ; and the results have been combined accordingly. 
The second result of the second series is obtained from cor- 
respondent eclipses ; and, like the former, by observations of 
this description, is considered of equal value with the mean of 
all the results found by correcting the Tables.* The differ- 
In drawing the conclusion, I have combined all the correspondent eclipses.
