The four cases, Mr. B----, Mrs. I----, Mr. C---- and Miss P----, presented the following generic symptoms: Inflammation of the mucous membranes of the nose, adventing yearly in the autumn. At first dryness, then watery discharges, finally involving the frontal sinuses and the conjunctival membrane.
