This is the "running at the nose" or "cold in the head," so frequently contracted. It consists of acute inflammation of the Schneiderian or mucous membrane of the nose, and the sinuses connecting with it. It causes considerable annoyance, and often creates some constitutional disturbance. It is caused by the partial application of cold, as to the back of the head or neck, to the feet, etc., and the effect is especially apt to be produced after perspiration from heat or exertion. When it reigns epidemically it is called influenza.

TREATMENT. -- It will usually subside without any treatment, but the subsidence can be greatly hastened by hot baths, a draught of ginger tea upon retiring, and the inhalation of some hot aromatic vapors, such as of balm, water-pepper, etc.
