The superior duct first ascends,then turning suddenly inward, forms an abrupt angle; the inferior duct,by descending, and then turning abruptly inward, forms a similar lachrymal sac is the upper extremity of the nasal duct. It con-sists of a mucous membrane covered by a fibrous expansion of the ten-dons of the orbicularis and tensor tarsi muscles. The nasal duct is ushort canal, three fourths of an inch long, running downward, back-ward, and outward to the inferior meatus of the nose, terminating an enlarged orifice. OF THE ORGAN OF HEARING.

The External Ear.—The external ear consists of the pinna, atunnel-shaped cartilaginous plate, which collects the vibrations of air,and the meatus, the tube which conveys them to the tympanum. The pmna piesents several folds and hollows upon its surface; aprominent rim, called helix, a curved ridge within it, called antihelix;this divides above, and encloses a space called scaphoid fossa; thepointed process over the opening of the ear is called tragus; a tubercleopposite anlilragus; the dependent portion of the pinna is the lobulus;a space between t
