With the removal of the crust relief is at once experienced, and if the discharge could be removed as fast as it forms the disease would not really be a source of offence. The general health would also improve, from the fact that an atmosphere tainted with a burden of decomposition would no longer be breathed. But in practice this cannot be attained, and it is imperative, after the chambers have been entirely cleansed, to cauterize the lining membrane throughout. I have been in the habit of beginning such cautery treatments with the middle turbinated bone, passing thence to the inferior turbinated bone, then to the roof of the nose in front of the sphenoidal sinus, and lastly to the septum. Small surfaces only should be covered at a single treatment, so that it may take a month or six weeks to finish a single series of applications. This treatment is almost always well borne, nothing ever ensuing beyond a slight headache or a temporary establishment of a serous discharge. Notwithstanding that the condition in question is one of atrophy, the reparative power of the mucous membrane remains apparently unaffected. At all events, no danger from sloughing is to be dreaded after such extensive destruction of tissue. The thin eschars separate within from three days to a week, leaving a healthy mucous membrane beneath. In one instance the cauterization had extended to a sufficient depth to expose the bone, and yet from this denuded surface no exfoliation took place, the parts healing rapidly and satisfactorily. No other local treatment is relied upon for fetid atrophic catarrh than the one mentioned. No disinfectant washes are required if the discharge is removed as described. Should the patient be so situated as to be unable to report regularly for its removal or treatment, a wash composed of one part of Labarraque's solution to sixteen parts of water may be ordered with advantage, or a solution of carbolic acid, gtt. j to fluidounce j, with a little glycerin, may be snuffed up the nose twice a day, or listerine, diluted one-half with water, may be used with advantage. The general health, of course, should be cared for, and any complications met. I have found that during the winter months arsenic and cod-liver oil are well borne, associated with minute doses of Lugol's solution. For adolescents earthy and the calcareous phosphates are indicated, and for all abundant exercise and careful dieting. When the symptoms have been relieved, the patient should be requested to report once a month, for it is not to be expected that all symptoms will disappear, and some point of advice can be advantageously offered at this interval.
