From the three positions of this star (1887-1911) we have for 
the proper motion of 3 Serpentis:

No other measures. The object in the field, referred to by 
Herschel, is h 1920; very diffused and bisection rather un¬ 
certain.

The four positions by 2 , A, Doo and P (1829-1910) give for 
the proper motion of A: 
o"o76 in io5?o 
The measure I have given by Lamont in 1836 is wholly 
wrong, and probably belongs to some other star. The relation 
at this time must have been about 29 0 : 45". 
The measures of 1856 and 1907 give for the proper motion 
of r| Coronae:

For comparison we have: 
1879.97 48?96 2x2^82 3n Bl. 
Further measures should be made after a suitable interval to 
give the best correction to the proper motion of AB. From the 
two positions that motion is: 
o"i97 in I52?3
