In pericarditis--the symptoms of which are fever and sharp pain under left nipple, radiating to the armpit, use the “Cascade” daily while the condition is acute; the wet sheet should also be employed daily, the temperature varying with the degree of fever. It is usually the sequel of rheumatism. In valvular insufficiency, which is caused by deposits upon the valves of the heart, the symptoms of which are principally difficulty of respiration, not much pain, but a feeling of uneasiness in the heart region, and a peculiar sound termed “the murmer,” to be detected by the stethoscope, the use of the “Cascade” will sometimes effect wonders. It arrests all further deposition of impurities in the blood, thus preventing any further accumulation on the valves, while the increased liquidity and purity of the blood enables it to re-absorb the existing deposits and thus restore normal action. Functional difficulties, as stated, chiefly result from digestive troubles, due to fermentation of food in the stomach and the consequent formation of gas, which frequently collects in large quantities, and by actual pressure impedes the heart’s action. The chief symptoms are shortness of breath, palpitation, and great irregularity of the heart’s action; sometimes the heart appears to miss a beat altogether. In such cases, a faithful observance of the formula of treatment for dyspepsia (see index) will accomplish surprising results. ANÆMIA. This is a disease of the blood, characterized by a deficiency of albumen and red corpuscles. It is a disease that more frequently affects women than men; the very young and the very old are most subject to it, and especially, if of a nervous, irritable or hysterical disposition. Among the exciting causes are defective hygiene, poor diet, want of, or excessive exercise, grief, or other strong emotions. The symptoms are great pallor, muscular weakness, frequent pulse, dizziness, breathlessness on slight exertion and fainting. There is another form of this trouble, known as Essential Anæmia, or Progressive Pernicious Anæmia, which almost invariably terminates in death; while in the first form, or simple anæmia, there is no reason whatever for a fatal result, if treated judiciously.
