XIII. Obstruction of the Lachrymal Duct. 



This duct is the one that carries off tears and superfluous moisture from 

 the eyes to the nose. It runs from the inner corner of the eyelids to 

 within two or three inches of the nostril, and empties on the floor of the

 Should this fail, the duct must be opened with a 

 probe. Take a fine elastic probe, about the size 

 of a knitting needle, and a foot long, and insert 

 it once a day for several days, and inject No. 73 

 with a fi'ie syringe.
