           TWELVE ARCHER'S VARIABLES ARE NONVARIABLES

  Twelve of the 24 variables in Leo, announced by Archer (1959), were observed 
in February and March using UBV photometer attached to the 91 cm reflector
at McDonald Observatory and V colour photometer attached to the 35 cm reflector
at Yunnan Observatory. At least 20 observations were made successively for
each star and covered more than the half of the period given by Archer. No
variations larger than the experimental deviations were detected for Archer's
number 3, 4, 7, 13, 14, 16, 17, 18, 19, 21, 22, 23. We arrived at the conclusion
that these stars are not variables. All data will be published in
Chinese.

  Table III and the legend of Figure 1 in I.B.V.S. No. 2501 is not legible
on most of the copies because of bad printing. For the sake of completeness
we repeat Table III and the figure caption here:
