42 Mr. Bugge’s Determination of 
two {ingle obfervations, it fcarce will bepoffible to avoid a fault 
of 2 minutes in the place of the node. 
If the inftrument is of a lefs force than a mural quadrant of 
6 feet, and the poffible faults in the altitudes greater, for 
example, io or 15 feconds, the refulting error in the place of 
the node may very eafily be calculated ; but the error in the 
node will be enormous, and the obfervations of no ufe for a 
nice aftronomer.

Mean 
9 21 50 8,5 
This mean agrees pretty well with the obfervations on the 
21ft, 27th, and 31ft of Auguft, which are neareft the node, 
and moft to be depended upon. 
The 2 1 ft of Auguft, at 9 h. 12' 26" true time at Co- 
penhagen, the heliocentric longitude of Saturn = ys. 21 0 49' 27", 
and the diftance from the node = 41 A The 27th of Auguft, at 
8 h. 23", the heliocentric longitude = 9 s. 22 0 o' i2 7/ ; 
therefore, in 5 days 23 h. 36' 5 7" Saturn has deferibed an arc 
of 1 o' 45 /7 , and io' 45" : 5 d. 23 b. 36' 57"=: 41" : x. Hence
