• If the seashell were held to the ear in an absolutely quiet room, no sound would be heard, because there would be no external forces to set into vibration the air within the shell. 伯莎M.克拉克. 科学通论.
• Seashells when held to the ear seem to contain the roar of the sea; this is because the air within the shell is set into sympathetic vibrations by some external tone. 伯莎M.克拉克. 科学通论.
• It is evident, from the quantities of seashells, and the bones and teeth of fishes found in high lands, that the sea has formerly covered them. 本杰明·富兰克林. 富兰克林自传.
