Plans to write a book on expression. Questions WB on orbicular muscle in screaming infant and function of muscle contractions in looking at a distant object.

Thanks for reply to queries. Spectroscope an instance of unimagined glorious prospects of science.

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.

Exceptional cases of frowning by children born blind have been reported to CD by R. H. Blair [see 8615]; CD asks WB for information and observations on the use of the muscles around the eye by those blind from birth.
