Summary:
Gives Charles Bell’s explanation of the contraction of the orbicularis during screaming and seeks confirmation of his view because the action is "the key-stone of a whole class of expressions". Curious to learn WB’s conclusion in regard to the relation between contraction of the orbicularis and secretion of tears. Notes that voluntary contraction of the orbicularis causes no tears.
