H 749 is in the central part of h 428. 
In his observations of 
the latter, Engelhardt has compared A with the three brighter 
stars by differences of R. A. and Decl. from which we have: 
AC 1887.06

83"3 in 
AD 1887.06 
85.1 
135-7 m 
AE 1887.06 
71.8 
155-6 in 
The differences in distance do not su 
ggest any real change, 
as they would be accounted for by the method of transists.

apparent proper motion of A:

The change in this is explained by the proper motion of A. 
1880.54 252?8o 237" 85 211 Bl. 
As these two positions give an apparent movement in A of 
about o"o?8, it is very probable that the 7.8 m star has a con¬ 
siderable motion of its own. This will appear from later 
measures of the two faint attendants.

From a 20-year interval in the micrometer measures the 
proper motion of the large star from meridian positions appears 
to be too small. The four positions by Ho, Doo and (3 give:
