SYmyroms. The symptoms of a typical at tack of influenza are headache with especially severe pain in the orbits and at the base of the oeciput : fever. with a temperature of ltel° or 10:3°, generally following an initial chill; great prostration and weakness with mental depression: pain in many of the joints and bones. and tenderness in the muscles: swell ing of the mucous lining of the nasal pas sages with increased flow of mucus: cough, with expectoration of small masses of thick, yellow ish or greenish mucus, accompanied by tender ness in the region of the breast-hone: rapid and generally weak pulse: buzzing noises in the ears: and slight tremor of the whole body. There is an inflammation of the throat, its mucous lining being congested and the palatal folds swollen and rigid. There may be sudden attacks of vertigo or of syncope, or of unconsciousness resembling that due to apoplexy. In some eases, in the place of severe catarrhal symptoms, an eruption. resem bling an urticaria, appears on the body. In others, the most severe symptoms are referable to the gastro•intestinal tract; the tongue being coated, the breath foul, the abdomen very tender on pressure, vomiting occurring, and the action of the bowels being irregular. In still other cases
the headache, backache, neuralgia (trigennual, occipital, ceiNi•obrachial or intercostal), my algia, insomnia, syncope, and vertigo are the most prominent symptoms. The predominance of sets of symptoms in certain classes of cases has led to the attempt by some physicians to divide influenza into respiratory, gastro-intes tinal, and nervous forms, of which the last has been fairly adopted. In all cases there is danger of pneumonia (q.v.). Both pleural and lungs are involved with surprising rapidity very early in sonic cases, with or without bronchial im plication. The pneumonia is lobular in vari ety, disseminated in separate areas throughout the lungs, with irregular and atypical invasion. It resolves by lysis and not by crisis, and predictions of its termination are impossible. The grippe pneumonia is much more fatal than the ordinary lobar pneumonia. The only safe place for a pa tient with influenza is in bed, during the attack, lest myocarditis (q.v.) or pneumonia should sud denly appear, and the patient's life lie actually jeopardized. and lest the effort to continue one's vocation in spite of undermined strength result in a protracted neurasthenia as a sequel to the attack.
