				<para>
    We present deep CCD photometries for the little known metal-poor
    clusters NGC 5694 and Terzan 8 down to V~24. NGC 504 has a blue
    horizontal branch, a very high radial velocity, a metallicity of
    [Fe/H]=-1.65+/-0.06, a reddening of E(B-V)=0.10+/-0.03, and an
    apparent distance modulus of (m-M)_v_=17.82+/-0.15. It is located at
    26.0+/-1.8kpc from the galactic center. The helium content derived
    from the ratio between the number of stars on the horizontal branch
    and the giant and asymptotic giant branches is consistent with that
    obtained for other clusters. Terzan 8 is a metal-poor
    ([Fe/H]=-1.81+/-0.10) moderately reddened (E(B-V)=0.20+/-0.05)
    cluster with a blue horizontal branch and apparent distance modulus of
    (m-M)_v_=17.25+/-0.15. It is located at 13.8+/-2.0 kpc from the
    galactic center. The c-m diagram and the luminosity function of NGC
    5694 and Terzan 8 are similar to the M92 ones. NGC 5694 and Terzan 8
    have ages close to that of the "classical" globular cluster M92.</para></description>
