                                   ABSTRACT

    Stromgren b,y photometry of the detached A-type eclipsing binary EG
    Serpentis was obtained.  Combined with the radial velocity curves in
    Popper [PASP, 98, 1312 (1986)], it was used to determine anew the
    system's parameters using the Wilson-Devinney code.  The age of the
    system is derived from a comparison with the Bertelli et al. [A&AS, 85,
    845 (1990)] isochrones.  Within the accuracy limits, the results are in
    accordance with expectations.
