And on the eighth day, after those (three) offerings have been performed in the same way, there is the same course of procedure. 'Adhvaryu!' he (the Hotri) says.--'Havai hotar!' replies the Adhvaryu.--'King Matsya Sâmmada,' he says; 'his people are the water-dwellers, and they are staying here;'--both fish and fishermen have come thither: it is these he instructs;--'the Itihâsa is the Veda: this it is;' thus saying, let him tell some Itihâsa. The Adhvaryu calls in the same way (on the masters of lute-players), but does not perform the Prakrama oblations.
