As these stars have shown no relative change in three- 
fourths of a century, I have connected a very faint star for the 
common proper motion: 
A and C (13.2)

The proper motion of A from the star catalogues is: 
Auwers o"o39 in 72?2 
Boss 0.052 in 95.5 
11107. 2 57, App. I. (6.5...6.5) 
R. A. 21 11 3i m 58 s Decl.+ 66° 12' 
Whatever proper motion there is, is common to both stars, 
but it is so small that it is very uncertain in amount and direc¬ 
tion. From the Groombridge Catalogue we have: 
A o"o40 in 207?1 
B 0.033 in 107.7 
To determine this motion hereafter, I have connected a small 
star:

The measures of this (1878-1909) give for the proper motion 
of 4 Pegasi: 
o"i42 in 77? o 
The meridian positions give: 
Auwers o'.'o89 in 69?7 
Boss 0.103 in 84.5 
It would be certain that the motion given by meridian obser¬ 
vations is too small, except that the first micrometer measure 
is on a single night. This will be corrected by later measures.

This will not sensibly change the proper motion of AB pre- 
viously given from the 
measures of C to 1904.

The very faint companion, B, was detected by Mr. Oliver J.
