is formed by the superior maxillary bone, os unguis, and os turbinatum inferius; and is seated in the outer paries of the nasal fossae. It is lined by a prolongation of the mucous membrane of the lachrymal sac; and its inferior orifice is furnished with a valvular duplicature. This duct transmits the tears, which have been absorbed at the great angle of the eye by the puncta lacrymalia, into the nasal fossae.
