A redetermination of the abundances of Na, Mg, Si, Ca, Sc, Ti, Cr, Mn, Te, Ni, and Ba in G dwarfs in the Hyades was carried out. The method was the same as that used in a previous determination (Wallerstein and Helfer 1959), but with new material at higher dispersion and with a different telescope and spectrograph. Another star of temperature even closer to that of the sun is included. The conclusions of the previous study are confirmed and strengthened; there appears to be a small and possibly significant general enrichment of the metals by approximately 20% in the Hyades stars when compared with the sun. Barium is again found to be overabundant by approximately a factor of 2. (auth)
