We  measured  the  radial  velocity  
 using our best
 spectrum,   that   obtained  in  February,  1997.
 The average value  of the  radial  velocity  from numerous  metal
 lines   (
) and from the
 
 absorption line (
) agree
 within  the accuracy of  measurement.
 This  radial  velocity  is consistent with a membership
 of an old population as suggested by the low
 metallicity  (see  Table1).  It  should be noted also that the
 value  of  radial  velocity  we  derived agrees with the value of
 
 which was given by Omont et al. (1993)
 from  CO data and 
 by Decin
 et  al. (1998)  from  optical spectrum. There is still no sign of
 an essential temporal variability of 
 for the object.
