One of the most distinguished French laryngologists, Dr. G. Poyet, was interviewed for the European edition of the N. Y. _Herald_ on the subject of hygiene for the singer. Although what Dr. Poyet says on some points is a repetition of matters already gone over here, while other points will be more thoroughly gone into than was possible for him in the space at his command, a summary of what this clever man had to say on a subject of such importance to the singer will serve capitally the purpose of this chapter. Dr. Poyet began by saying that, since the voice has intimate relationship with the entire organism, it follows that a well-understood hygiene should concern the totality of the functions. First of all, it is indispensable to avoid any cause of disturbance of the circulation, and particularly of the pulmonary functions. "The singer, as much as possible, should inhabit sufficiently large apartments. He should avoid rooms warmed by apparatus which may produce carbonic acid or which remove from the air the watery vapor it contains normally. Every day on rising he should practise exercises in deep breathing and, if possible, some of the gymnastic exercises which it is possible to practise in a room. Walking is undoubtedly the best exercise, and every singer who is careful of the soundness of his lungs--which is equivalent to the soundness of his voice--should walk for an hour every morning before his repast." (This advice of Dr. Poyet can hardly be taken literally, and should be determined largely by the physique of the individual.) In order to avoid colds, bronchitis, sore throat, catarrhal laryngitis, the singer should regulate in a fitting manner the thickness of his clothing in accordance with the prevailing temperature. If by misfortune he catches cold, a little laryngitis, a coryza, all of which cause hoarseness, he should immediately abstain from singing. Neglect of this rule may bring about the persistence of vocal accidents often very long in curing. It is because professional singers cannot interrupt their work in such cases that they more often than any others suffer from laryngitis and above all in the so dangerous form of chronic inflammation of the vocal cords, which determines the deplorable "singers' nodules." The cutaneous secretions should be watched in persons who have need of a clear voice. Almost all catarrhal affections of the respiratory organs are due to chills. Advice is therefore given to every person who has practised violent singing-exercises, which cause perspiration, immediately to change his clothing after having been rubbed down with a horsehair glove or with flannel sprinkled with alcohol.
