    or chronic inflammation which is started by the com- plications resulting from these sinus lesions. An in- stance of this is the aural diseases which result from the formations of polypi dependent upon accessory sinus diseases. In such cases the effect of the affection of sinus upon the disease is secondary. The direct causes of the aural lesion are either sepsis, or interference with physiological aeration, or stenosis. 8. Other lesions of the naso-pharynx or pharynx produce aural disease by interference with drainage, extension of inflammation, or by the production of chronic congestion. In this way we account for the role played by adenoids in the production of aural disease, as well as for the chronic congestion produced by the faucial tonsils and by the presence of follicular enlargement of the mucous glands of the pharynx. 9. Certain medicaments or other foreign matter may produce aural diseases, either directly from being forced into the ear, or by setting up an inflammation in the Eustachian tube which afterwards spreads to the middle ear. One need only recall the effect of peroxide of hydrogen, the injection of water by means of the nasal douche, the effect of irritating applications such as iodine, carbolic acid, and cauterizants to the region at the mouth of the tube or the naso-pharynx, and to remember the results which we have all seen from blood being forced into the tube by coughing or sneezing, or the effects of small particles of food forced into the tube during vomiting, as well as involvements of the middle ear following the use of the post nasal plug or other forms of packing, to realize how frequently these agents are active in producing aural lesions.
