A photoelectric survey of fourteen normal Hyads of spectral types A-F within the Delta Scuti instability strip has revealed that 36% of these stars are variable. With previously discovered variables taken into account, the minimum incidence of Delta Scuti variability in the cluster is 37%. This is consistent with the results found in other galactic clusters. An additional variable, 60 Tauri, with spectral classification Am was detected during this survey. 60 Tauri lies within the predicted instability strip for Am stars as given by Cox, King, and Hodson (1979). No significant differences in the mean rotational velocities were found between the variable and constant stars of normal A-F spectral types.
