  A leading order determination of the gluon density in the proton has been
performed in the fractional momentum range $1.9 \cdot 10^{-3} < x_{g/p} < 0.18$
by measuring multi-jet events from boson-gluon fusion in deep-inelastic
scattering with the H1 detector at the electron-proton collider HERA. This
direct determination of the gluon density was performed in a kinematic region
previously not accessible. The data show a considerable increase of the gluon
density with decreasing fractional momenta of the gluons.
