Any powder that contains pumice-stone, cuttle-fish bone, charcoal, or gritty substances of any sort, as many unfortunately do, is injurious, because these scratch the enamel of the teeth and give the acids in the mouth a chink through which they may begin to attack the softer dentine underneath the "glaze" of enamel.
"A Handbook of Health"
Woods Hutchinson

"Dickens As an Educator"
James L. (James Laughlin) Hughes
Anonymous assailants may be likened to the cuttle-fish, which employs the inky secretions it forms as a means of tormenting its enemy and baffling pursuit.
