ASTHMA is one of the diseases in which additions to exact knowledge during recent years have been few and comparatively unimportant. I wish to call attention to the form of asthma – in my belief the form most frequently seen – in which the disease depends largely upon the interaction of an abnormally sensitive nasal mucous membrane, and in this respect an abnormally excitable condition of a portion of the nervous system. ... Nothing gives more relief to the majority of those who suffer from this disease than the use of various nasal sprays of cocaine.
