                                    In previous papers we have published preliminary results on the stellar
oxygen-abundance gradient in M33 by using B-type supergiants. In the
present study, we include one new B-supergiant and derive effective
temperatures and gravities for these stars. The determination of
atmospheric parameters is based on analyses of silicon ionisation
balance.
