Observations of the four brightest of the globular clusters in the Fornax dwarf spheroidal galaxy yield radial velocities whose accuracy is + or - 10 km/s. The most prominent spectral features are the Mg triplet and the Balmer lines. The mean relative velocities for the two nights of observation are given. The velocity dispersion of the four clusters is 6 km/s; there is no evidence from the data for the predicted large-velocity dispersion in the Fornax dwarf galaxy. At a 95 percent confidence level, M/Lv in Fornax is less than 8, a value closer to that of the globular clusters. The absolute radial velocities are determined by using the spectra of several Small Magellanic Cloud clusters. It is found that the three brightest globular clusters in the Fornax dwarf galaxy have a radial mean velocity of -88 km/s with respect to NGC 121, or 66 + or - 25 km/s.
