The duration at Cajaneburg was the fhorteft ex- 
cept at Tobolfkij with which if we compare the du- 
ration obferved at Madrafs the parallax is 9", 948 : 
and by taking a mean of the parallax deduced from 
a comparifon of the obfervation at Madrafs with 
thofe of Tobollki and Cajaneburg, the parallax 
is 9 ,762. r 
The obfervations at the above places agree as well 
together as can be expeded from fuch lmall differ- 
ences in the duration, which mud: in fome meafure 
be influenced by the neceffary and unavoidable errors 
in obfervation.
