  We present moderate-resolution Keck spectra of nine candidate globular
clusters in the possible merger-remnant elliptical galaxy NGC 3610. Eight of
the objects appear to be bona fide globular clusters of NGC 3610. We find that
two of the clusters belong to an old metal-poor population, five to an old
metal-rich population, and only one to an intermediate-age metal-rich
population. The estimated age of the intermediate-age cluster is 1-5 Gyr, which
is in agreement with earlier estimates of the merger age, and suggests that
this cluster was formed during the merger. However, the presence of five old
metal-rich clusters indicates that a substantial number of the metal-rich
clusters in NGC 3610 likely came from the progenitor galaxies, although the
global ratio of old to intermediate-age metal-rich clusters remains very
uncertain.
