J. M. Campbell, Notes on the natural history of the Bell Rock (1904)
“ At high water they come quite close to the tower, and their antics are seen to advantage from our balcony. Rolling over each other, they make for the bottom, gliding along the rocks like hounds hunting in couples; then with a rush they are on the surface, floating bolt upright, with their muzzles almost touching, staring with their large, expressive eyes into each other’s face. An almost human touch was given to their play by one taking the head of the other between his fore-flippers, as if about to salute him, or more likely her, in the orthodox fashion. ”
