The left nasal duct was however shown to be intact, as water injected by the canaliculus passed freely into the nose.
The Auricular Branch (ramus auricularis; nerve of Arnold) arises from the jugular ganglion, and is joined soon after its origin by a filament from the petrous ganglion of the glossopharyngeal; it passes behind the internal jugular vein, and enters the mastoid canaliculus on the lateral wall of the jugular fossa.
The lesser superficial petrosal nerve sometimes passes through a special canal (canaliculus innominatus of Arnold) situated medial to the foramen spinosum.
Each has two fine processes, the outer one passing into a dental canaliculus, the inner being continuous with the processes of the connective-tissue cells of the pulp matrix.
In this way the entire thickness of the dentin is developed, each canaliculus being completed throughout its whole length by a single odontoblast.
On the ridge of bone dividing the carotid canal from the jugular foramen is the inferior tympanic canaliculus for the transmission of the tympanic branch of the glossopharyngeal nerve; and on the wall of the jugular foramen, near the root of the styloid process, is the mastoid canaliculus for the passage of the auricular branch of the vagus nerve.
# -- _Wounds of the eyelids_ are liable to be complicated by damage to the lachrymal apparatus, leading to stenosis of the canaliculus and persistent watering of the eye.
Keeping the canal relaxed by relaxing his hold on the lid, the surgeon now gently wriggles the probe along the canaliculus, gradually stretching it as the probe advances, so as to avoid catching of the sides of the canal before the point of the instrument, till he is satisfied that it has fairly entered the nasal duct.
 Rough diagram of Bowman's operation, showing the grooved director in the punctum, and the knife in the groove just before it slits up the canaliculus.
The principle of Mr. Bowman's most excellent operation is, that the punctum, canaliculus, and nasal duct resemble in many respects the urethral passage, and in cases of stricture require to be treated on the same principle.
