The A. G. positions give 54T4 (1881.0). 
The interval is too short for a high degree of accuracy in the 
proper motion. Later measures will give a better value:

No other measures, h 462 is closely following; has no 
central condensation for accurate setting of the wires.

The R. A. of h 462 is doubtful in Dreyer. From the compari¬ 
son with Schj 7 we have for the place of h 462:

The only other measures of C are those given in Part II 
of the General Catalogue. The change in distance corresponds 
to a proper motion in A of about o"o6. 
The planetary nebula h 464 is about 3 j 4 m preceding. My 
former measures comparing the central star with one in the 
nebula, and another following, are given in Pub. Lick. Obsy.
