The prevalence of throat troubles is so marked in America, and by no means least so in this city, that if one hundred individuals, collected at random, had their throats examined, it is probable that four out of every five would be found to have these delicate organs more or less affected. Whatever cause may be assigned by the medical expert in each particular case, the importance of a thorough mastery of the art of correct breathing can hardly be insisted upon too strongly. If it be urged that the widely distributed works of Behnke and others must have put an end to any general ignorance of the importance of this branch of vocal training, I can only reply that a defective style of breathing is by no means uncommon even in public singers, while among amateurs it is so rare that a perfect management of the breath excites in a critical observer a feeling of gratified surprise. The name and works of Behnke have, of course, been known in this country for a considerable time, but some of his statements are too striking to be omitted in an article on this subject. When lecturing at the Tonic Sol-fa College, London, he took ten students and measured their lung capacity in cubic inches, by means of the spirometer, with wrong or "collar-bone" breathing. He then showed them how to breathe correctly, that is, midriff and rib breathing. The average increase among the ten was twenty-five cubic inches of air; the least increase twelve inches, and the greatest forty-five. He adds: "I imagine that these figures are more eloquent than any words, and I think it superfluous to make any further comment on them."--('Mechanism of the Human Voice,' page 20.) Now, putting aside the extreme increase of forty-five inches, let anyone consider what an increase in lung capacity of twenty-five cubic inches of air must mean to the vocalist in the execution of difficult passages, to the speaker using his voice by the hour, and, lastly, to the running athlete. It will surprise a young man commencing vocal training to inform him that, at the same time, he will become a better man in the gymnasium and the race; but unless good lungs are an advantage to the athlete in name only, the above figures tell their own tale. I may add that, in teaching young men and boys, I always put this view of the subject before them, knowing that it will be an incentive to their acquiring a thorough mastery over the interesting art of "taking breath." Correct breathing cannot _cure_ disease. The medical expert must do that. But it will _prevent_ disease; and when the throat, under proper treatment, has been brought to a healthy state, it will assuredly be the chief means of keeping it in that condition. The following is a striking instance to the same effect:
