  The reaction $^{12}$C + $^{13}$C at 95 MeV bombarding energy is studied using
the GARFIELD + Ring Counter apparatus located at the INFN Laboratori Nazionali
di Legnaro. In this paper we want to investigate the de-excitation of $^{25}$Mg
aiming both at a new stringent test of the statistical description of nuclear
decay and a direct comparison with the decay of the system $^{24}$Mg formed
through $^{12}$C+$^{12}$C reactions previously studied. Thanks to the large
acceptance of the detector and to its good fragment identification
capabilities, we could apply stringent selections on fusion-evaporation events,
requiring their completeness in charge. The main decay features of the
evaporation residues and of the emitted light particles are overall well
described by a pure statistical model; however, as for the case of the
previously studied 24Mg, we observed some deviations in the branching ratios,
in particular for those chains involving only the evaporation of $\alpha$
particles. From this point of view the behavior of the $^{24}$Mg and $^{25}$Mg
decay cases appear to be rather similar. An attempt to obtain a full mass
balance even without neutron detection is also discussed.
