  We report early FUSE observations of the very hot DA white dwarfs PG1342+444
and REJ0558-371. Detection of photospheric absorption lines allows us to
estimate the abundances of C, O, Si, P, S and Fe, the first measurements
reported for DA stars at such high temperatures. Values of Teff and log g
determined for PG1342+444 from the Lyman line series disagree with the results
of the standard Balmer line analysis, an issue that requires further
investigation.
