$\begin{figure} \par\includegraphics[width=8.8cm,clip]{aa3832f1.eps}\end{figure}$ Figure 1: Mass distribution for all 112 massive white dwarf stars of our catalogue (gray scale). The wide-binned histogram shows the local maximum of the mass distribution in the range $1.0{-}1.05 ~M_{\odot}$ . The inserted dark tone histogram with finer resolution of $0.01 ~M_{\odot}$ clearly suggests that the local maximum of the WD mass distribution is located at ${\approx} 1.04 ~M_{\odot}$ .

$\begin{figure}\includegraphics{aa3832f3.eps} \end{figure}$ Figure 3: Mass distribution for nonmagnetic massive white dwarf stars. The local maximum at $1.04 ~M_{\odot}$ , as shown in Fig. 1, should be attributed solely to the above nonmagnetic white dwarfs.

Note that the incidence of magnetism increases with white dwarf mass. The dashed line denotes the average fraction of magnetic white dwarfs among isolated massive WDs.

$\begin{figure} \par\includegraphics[width=8.8cm,clip]{aa3832f5.eps} \end{figure}$ Figure 5: Number distribution of magnetic (dark tone) and nonmagnetic (light tone) white dwarfs. The distributions of both types of massive white dwarf stars a very sharp maximum in the range $5000 \le {T_{\rm eff}}< 10~000$ K. Computations show that the relative fraction of magnetic white dwarfs vs. ${T_{\rm eff}}$ remains almost constant, $0.2 < N_{\rm mag}/N_{\rm tot} < 0.4$ up to ${T_{\rm eff}}= 40~000$ K.
