Children bear attacks better than adults, and in their case the disease is usually periodic in its recurrence, but as the years advance it tends to become more erratic both in its mani festations and time of appearance, and is apt to disappear at puberty. Persons past middle age are not apt to rid themselves of it, al though they may live to a good old age and die of some other disease. Much can be done to prevent future attacks if the cause of the paroxysm can be determined and properly treated. Constipation, over-eating, and eating at bedtime should be avoided. An operation upon the nose may be necessary to remove a growth that is causing undue pressure upon the nasal septum. It is often advisable to move to another climate or locality. Endeavor should be made to strengthen the nervous system, if that be at fault; breathing exercises are often helpful. Another method, which has come into prominence of late, is to restore the stability of the respiratory centre by cauterizing the septal mucous membrane, and combining this with hygienic measures. This is performed by painting one side of the nasal septum with a few drops of cocaine and resorcin, and then drawing a line with a galvano-cautery point from a spot opposite the middle turbinated body, forward and slightly downward for a little less than half an inch. After an interval
of six or seven days the operation is repeated on the other side. The heart, kidneys, gout and rheumatism should be treated separately and without reference to an asthmatic attack. During the attack a hypodermic injection of 54 grain of morphia generally gives relief ; amyl nitrite inhaled or nitroglycerine 1/100 grain in jected lessens the severity of an attack. Adren alin by hypodermic injection is claimed by some to be very useful. Cigarettes of various kinds usually composed of a combination of the leaves of belladonna, stramonium and hyoscyamus are used and help some patients very much. Inhalation of fumes from burn ing blotting paper soaked in potassium nitrate (1/15) is also used. In the interval remedies recommended for internal use to prevent and lessen the severity of future attacks are potas sium iodide, belladona, lobelia, hyoscyamus and grindelia robust.
