These positions compared with a mean of the measures by 
Engelhardt give for the proper motion of the large star: 
Measures of C o"230 in 226°.$ 
Measures of D 0.156 in 258.0 
These measures should be continued. 1 he motion of the 
large star from the catalogues is:

My measures indicate a proper motion 
in declination for one 
of the stars of about 
o"i. The distance by South in 1825 is 
much too large.

The four positions of AB by 2 , A, Doo and P (1830-1908) 
give for the proper motion of A:

A comparison of this with the measure of 1898 by Doolittle 
gives practically the same proper motion for A. 
No other measures. The object in the field, h 506, referred 
to by Herschel, was not noticed.

The time interval of 17 years should be extended for the best 
result. From these measures we have for the proper motion
