Excerpt from Philadelphia Medical Times, 1881-1882, Vol. 12: A Bi-Weekly Journal of Medical and Surgical Science The most prominent and, to the patient, most annoying symptom of catarrh is a copious discharge of thick, ropy mucus, which accumulates in the posterior nares, and from there descends into the naso pharynx, causing a feeling of fulness in that region which the patient endeavors to te lieve by hawking. This mucus is the per verted secretion of the hypertrophic glands in the mucous membrane, and is prevented from flowing through the natural channel, the anterior nares, by the presence of the anterior or posterior hypertrophies.
