Difficult Breathing.—If caused by gas, soda, hot whisky or brandy will relieve. If caused by too fast beating of the heart, give digitalis as above directed. If caused by dropsy, the regular remedies for dropsy. If the dropsy is due to scanty urine you can use infusion of digitalis, dose one to four drams; or cream of tartar and epsom salts, equal parts, to keep the bowels open freely.
PHYSICIAN'S CAUTIONS:—Quiet the patient's mind and assure him there is no actual danger; moderate exercise should be taken as a rule with advantage. Regular hours should be kept and at least ten hours out of twenty-four should be spent in lying down. A tepid bath may be taken in the morning, or if the patient is weakly and nervous, in the evening, followed by a thorough rubbing. No hot baths or Turkish bath. Tea, coffee and alcohol are prohibited. Diet should be light, and the patient should avoid overeating at any meals. Foods that cause gas should not be used. If a smoker the patient must give up tobacco. Sexual excitement is very pernicious, and the patient should be warned especially on this point. Absolute rest for the distressing attacks of palpitation which occur with nervous exhaustion. In these cases we find the most distressing throbbing in the abdomen, which is apt to come after meals, and is very much aggravated by the accumulation of gas.
Diet.—A person with heart disease should not bring on palpitation from over-eating or eating the wrong kind of food. Such a person dare not be a glutton. The diet must be simple, nutritious, but food that is easily digested. Any food that causes trouble must be avoided; starchy foods, spiced foods, rich greasy foods, are not healthy for such a person. The stomach must be carefully treated by such a patient. The bowels should move daily. The kidneys should always do good work and pass enough urine and of the right color and consistency. Stimulants like alcohol, tea and coffee are not to be used. Weak cocoa is all right in most cases. Hot water, if any drink must be taken, at meals. Such a patient in order to live and live comfortably, must take life easy. He cannot afford to run, to over lift, or over exert, to walk fast upstairs, hurry or to "catch the car." He must not get angry or excited. Games of all kinds that have a tendency to make him nervous must be avoided. The same caution applies to exciting literature. In short, a patient with organic heart disease must be a drone in the hum of this busy, fast-rushing life, if he would hope to keep the spark of life for many years. Sleep, rest and quiet is a better motto for you than the strenuous life.

The Heart.—The heart is the central organ of the entire system and consists of a hollow muscle; by its contraction the blood is pumped to all parts of the body through a complicated series of tubes, termed arteries. The arteries undergo enormous ramifications (branchings) in their course throughout the body and end in very minute vessels, called arterioles, which in their turn open into a close meshed network of microscopic (very minute) vessels, termed capillaries. After the blood has passed through the capillaries it is collected into a series of larger vessels called veins by which it is returned to the heart. The passage of the blood through the heart and blood vessels constitutes what is termed the circulation of the blood. The human heart is divided by a septum (partition) into two halves, right and left, each half being further constricted into, two cavities, the upper of the two being termed the auricle and the lower the ventricle. The heart consists of four chambers or cavities, two forming the right half, the right auricle and right ventricle, and two forming the left half, the left auricle and left ventricle. The right half of the heart contains the venous or impure blood; the left the arterial or pure blood. From the cavity of the left ventricle the pure blood is carried into a large artery, the aorta, through the numerous branches of which it is distributed to all parts of the body, with the exception of the lungs. In its passage through the capillaries of the body the blood gives up to the tissues the material necessary for their growth and nourishment and at the same time receives from the tissues the waste products resulting from their metabolism, that is, the building up and tearing down of the tissues, and in so doing becomes changed from arterial or pure blood into venous or impure blood, which is collected by the veins and through them returned to the right auricle of the heart.
From this cavity the impure blood passes into the right ventricle from which it is conveyed through the pulmonary (lung) arteries to the lungs. In the capillaries of the lungs it again becomes arterialized by the air that fills the lungs and is then carried to the left auricle by the pulmonary veins. From this cavity it passes into that of the left ventricle, from which the cycle once more begins. The heart, then, is a hollow muscular organ of a conical form, placed between the lungs and enclosed in the cavity of the pericardium. It is placed obliquely in the chest. The broad attached end or base is directed upwards, backwards and to the right and extends up to the right as high as the second rib and the center of the base lies near the surface underneath the breast bone. The apex (point) is directed downwards, forward and to the left and corresponds to the space between the cartilage of the fifth and sixth ribs, three-fourths of an inch to the inner side, and one and one-half inches below the nipple, or about three and one-half inches from the middle line of the breast bone. The heart is placed behind the lower two- thirds of the breast bone and extends from the median line three inches to the left half of the cavity of the chest and one and one-half inches to the right half of the cavity of the chest.
Size: In adults it is five inches long, three and one-half inches in breadth at its broadest part and two and one-half inches in thickness. Weight in the male ten to twelve ounces; in the female eight to ten. It increases up to an advanced period of life. The tricuspid valve (three segments) closes the opening between the right auricle and right ventricle. Pulmonary semilunar valves guard the orifice of the pulmonary artery, keeping the blood from flowing back into the right ventricle. The mitral valve guards the opening to the left ventricle from the left auricle. The semilunar valves surround the opening from the left ventricle into the aorta and keep the blood from flowing back. If any one of these valves becomes diseased it may not thoroughly close the opening it is placed to guard and then we have a train of important symptoms.

PERICARDITIS.—This is an inflammation of the pericardium, the sac containing the heart.
Primary or First Causes.—They refer in this disease to a peculiar constitution. Children that have a tuberculous constitution are more liable to this disease. Acute rheumatism or tonsilitis are the causes and this trouble follows or goes with them. Infectious diseases also cause it.
