• Seven Raman lines of the tetragonal BaTi0_3 single crystals, excited by the Hg-c line, have been observed at 359, 416, 502, 513, 736, 823 and 1181cm^<-1> from the c-line. The three lines of higher frequencies are interpreted to be corresponding to the lattice vibrations of higher mode. A possible explanation of the four lines of lower frequencies is presented as corresponding to the fundamental modes of vibration in tetragonal BaTi0_3. A possibility is pointed out that the "ferroelectric mode" splits into two spccies, of which frequencies are near 340 cm^<-1> and near 34 cm^<-1>, respectively. The Raman line located at 359 cm^<-1> is interpreted to be corresponding to the former species.
