  The extreme helium-rich atmospheric composition determined for the halo white
dwarf WD 0346+246 is reexamined. This solution is shown to be improbable from
an astrophysical point of view when accretion of hydrogen and metals from the
interstellar medium is taken into account. An alternate solution is proposed
where hydrogen and helium are present in the atmospheric regions in equal
amounts. The best fit at Teff=3780 K, log g=8.34, and N(He)/N(H)=1.3 is
achieved by including in the model calculations a bound-free opacity from the
Lyman edge associated with the so-called dissolved atomic levels of the
hydrogen atom, or pseudo-continuum opacity.
