We have the following of two of these stars: 
AC 1891.79 3i4?o2 44"87 2n Eng 
AD 1891.79 266.25 100.37 in Eng 
If the early measures had been made on a greater number 
of nights, the result of a comparison with the present meas¬ 
ures would be more accurate. 
AC R. A.—o"i30 Decl. — o"o24 
AD 0.178 0.024 
— 0.154 —0.024 
Hence the most probable proper motion of A is: 
0IT56 in 261? 1 
The meridian positions give :

No other measures. A 12.5 m star about the same distance 
in 204°. A. G. Harvard gives the principal star a proper motion 
of o"o3i in 270°.

My measures of this (1903-1910) give for the proper motion 
of A: 
o'.'38o in 103? 1 
The measures should be continued for a final value. From

The several measures of both companions should give the 
proper motion of the principal star with great accuracy.
