To make the way in which respiration is carried on clearer still, I quote the following interesting and lucid account from Huxley's "Elementary Physiology," fourth edition, p. 104. He compares the breathing apparatus to "a sort of bellows without a valve," in which the chest and the lungs represent the body of the bellows, while the windpipe is the pipe; "and the effect of the respiratory movement is just the same as that of the approximation and separation of the handles of the bellows, which drive out and draw in the air through the pipe. There is, however, one difference between the bellows and the respiratory apparatus, of great importance in the theory of respiration, though frequently overlooked, and that is, that the sides of the bellows can be brought close together so as to force out all, or nearly all, the air which they contain, while the walls of the chest, when approximated as much as possible, still enclose a very considerable cavity; so that even after the most violent expiratory effort, a very large quantity of air is left in the lungs."

=Respiration=, consequently, consists of two acts--namely, inspiration and expiration. Inspiration may be produced in three different ways--(1) By pushing the chest forward and flattening the midriff, so as to compel the lungs to _descend_ and to increase in volume in order to fill the empty space created by this movement; (2) by extending the ribs _sideways_; and (3) by _drawing up_ the upper parts of the chest--namely, the collar bones (pl. III, C C) and the shoulder blades. In scientific works the first is called diaphragmatic or abdominal,[B] the second lateral or costal, and the third clavicular or scapular breathing. As, however, these terms convey no meaning to the general reader, I prefer to speak of--(1) Midriff Breathing; (2) Rib Breathing; (3) Collar-bone Breathing. In taking a full, deep inspiration, midriff breathing and rib breathing take place almost together and assist each other--that is to say, the midriff contracts and flattens, and immediately afterwards the ribs extend sideways; with this difference, however, that in men the action of the midriff takes a larger share in the work than the ribs, while in woman, on the contrary, the movement of the ribs is greater than that of the midriff.

By way of illustrating this curious difference of breathing in men and women, the following anecdote, which has the recommendation of being strictly true, may perhaps amuse the reader. Some time ago a troupe of "Female Minstrels," calling themselves, I believe, "The American Amazons," made a tour through this country. Their faces were blackened in the orthodox fashion, and they were in male attire, wearing tight-fitting garments of a peculiar kind. Two friends, both medical men, went to hear them (or perhaps to see them, I am not sure which), when Mr. A remarked that two of the performers were men. Mr. B did not see it, even when the individuals were pointed out to him, and asked his friend for the reasons for his opinion. "Why," said Mr. A, "I see it by their abdominal breathing!" And sure enough Mr. B now saw it too, and there was no mistake about it; for in the two suspected individuals the abdomen was evidently moving in respiration, while in all the others no movement was perceptible excepting that of their chests.

The combined forms of midriff and rib breathing are the right method of inspiration, while collar-bone breathing is absolutely wrong, and should never be made use of. The reasons of this are not far to seek. The lower part of each lung is large and broad, while the upper part is cone-shaped, and very much smaller. It is self-evident, therefore, that by downward and sideways expansion (enlarging the _lower_ part of the lungs) you will inhale a much greater quantity of air than by drawing up the collar-bones. This consideration alone should suffice to prove the utter falseness of collar-bone breathing. Collar-bone breathing has also the additional disadvantage of causing much fatigue, because all the parts surrounding the upper region of the lungs are hard and unyielding, so that a great amount of resistance has to be overcome (the "_lutte vocale_" of French authors), while the very opposite is the case with the lower part of the lungs.

Mr. Lennox Browne, who was, I believe, the first to direct the attention of English readers to this matter, says,[C] "Clavicular [collar-bone] breathing is a method of respiration totally vicious, and to be avoided. By it the whole lower part of the chest is flattened and drawn in, instead of being distended; consequently the lower or larger part of the lungs is not inflated. It is a method never exercised by nature in a state of health, but only when, from disease, either the abdominal or chest muscles cannot act; and it is the method least efficacious in filling, as it is the one calculated to most fatigue the chest; for it compresses the vessels and nerves of the throat, and this leads to engorgement and spasmodic action of the muscles."

We may well pause here and give another moment to the consideration of this most important subject. The lungs, as we have seen, are the bellows of our vocal organ; they supply the air which is the motive power on which the voice depends. Without air no tone can be produced. Nay, more, life itself must cease without it. Breathing goes on regularly while the voice is silent; but in speaking and singing both inspiration and expiration have to be regulated according to the nature of the phrases to be spoken or sung. If the speaker does not know how to take breath and how to control the expiration, his delivery will of necessity be jerky and uncertain. But in the singer it is even more important that he should be able to fill his lungs well, and, having done this, to have absolute command over his expiration; because while the speaker can arrange his sentences, his speed, and his breathing-places very much at his own pleasure, the singer is bound by the music before him. It must, therefore, be his aim to cultivate a proper method of breathing with the object of first getting, with the least possible fatigue, the largest possible amount of air in the most scrupulously careful manner, so as to prevent even the smallest fraction of it from being wasted. Yet how seldom is breathing systematically practised as an indispensable preliminary to the production of tone! I have no hesitation in saying that the subject is, in many instances, dismissed with a few general observations. Pupils, of course, take breath somehow, and teachers are glad to leave this uninteresting part of the business, and to proceed to the cultivation of the voice.

It may be as well to add that what has been said so far about right and wrong methods of breathing is not by any means mere theory, but that any one can convince himself of the truth of the rules laid down by making a few experiments with the spirometer, an instrument for measuring the breathing power of the chest by indicating on a dial the exact number of cubic inches of air expelled from the lungs. This breathing power will be found to vary according to the way in which the inspiration has been accomplished. In my own case, for instance, the spirometer should register, according to the table of comparative height and breathing power compiled by John Hutchinson, 230 cubic inches. Having suffered from severe attacks of bleeding from the lungs, my maximum with midriff and rib breathing is only 220, but with collar-bone breathing I barely reach 180!

During the Summer Session of the Tonic Sol-fa College I carefully tested the breathing capacity of ten students, and found that there was an average excess of midriff and rib breathing over collar-bone breathing to the extent of 25 cubic inches: the least amount of their increased power was 12 cubic inches, and the greatest was 45! I imagine that these figures are more eloquent than any words, and I think it superfluous to make any further comment on them.

I am strongly of opinion that breathing exercises, especially in the case of intending public singers, should always be carried on with a spirometer,[D] because that instrument enables us with the greatest accuracy to check results which otherwise can only be guessed at.

If this suggestion were acted upon we should certainly no longer be distressed by that intolerable and never-ceasing tremolo which now so frequently mars many, in other respects, fine voices. It is a curious, and at first sight unaccountable, circumstance that this great fault is specially noticeable amongst French singers. But at the Conservatoire de Musique in Paris students are deliberately taught the wrong method of inspiration; for, as we gather from the "Méthode de Chant du Conservatoire de Musique," they are told to "flatten [or draw in] the abdomen" and to "bulge out the chest." Thus the mystery is at once cleared up, because the tremolo arises almost invariably from a weakness of the muscles of the midriff or diaphragm, to which attention has already been called in these pages. Owing to the abdomen being drawn in, the midriff never properly contracts; the muscles are not sufficiently exercised, and consequently have not power enough to resist the pressure that is brought to bear upon them in singing. They tremble, and this trembling being communicated to the lungs, which are resting upon them, the stream of air they give forth, loses its evenness and continuity, with the result I have just stated. It will be seen from the above explanation that this tremolo, one of the greatest vices besetting modern singing, and which has hitherto been held by many to be incurable, may be got rid of completely, though perhaps not very quickly, by the simple remedy of lung gymnastics on the right principle. The tremolo may certainly also arise from weakness of some muscles in the voicebox or larynx, by which the tension of the vocal ligaments is diminished and increased in rapid alternation. But this is a case for a medical man, which does not fall within my province to discuss, though I am justified in saying, on the authority of Mr. Lennox Browne,[E] that even in many of these cases the effect is clearly attributable to faulty breathing, since there is seldom any local disease of the larynx; while exercise on a right method of breathing will cure the spasmodic action of the laryngeal muscles with but little or no medical treatment.

* * * * *

I need scarcely add that there is yet another kind of tremolo, which, being absolutely under the control of the performer, is one of the chief ornaments of song, and to which the observations just made in no way apply.

* * * * *

In addition to the involuntary tremolo there are a number of other afflictions, "Clergymen's sore throat" amongst them, which are admitted by eminent medical authorities to be due to collar-bone breathing, and which may be entirely cured by proper lung gymnastics, or, in other words, by breathing exercises on the right principle; that is to say, by calling into play the muscles of the abdomen and of the lower part of the chest. This is a subject which is little understood by singers and public speakers, many of whom would be amazed at the sometimes most wonderful results produced by such simple means. I will therefore quote a case in point which came under my notice quite recently, and which will give the reader an idea of the importance of proper breathing:

Mr. X, a tall thin young man, engaged in evangelistic work, suffered from a "weakness of voice," which he found a great hindrance to his success. He therefore consulted Mr. Lennox Browne, who at once told him that he had no disease of any kind, and sent him to me for a course of breathing exercises. I found that Mr. X chiefly spoke in a child's voice, over which, moreover, he had very little control; and when I requested him to take a deep inspiration, he drew in his abdomen, bulged out his chest, and raised his collar-bones. The spirometer only registered 200 cubic inches instead of 260, which, according to Hutchinson's table, was his mean.

My course was, therefore, plain. I made him stand in an easy natural position, neither allowing him to bulge out his chest, nor to draw in the abdomen, and then instructed him how to acquire some control over his midriff and the lower muscles of the chest. It may be observed here, in passing, that we can, in a state of health, contract and relax these muscles at will, just as easily as we can bend a finger, and that this power, when lost through disuse, can be regained with little difficulty. In Mr. X's case this process was particularly speedy, with the result of increasing his breathing power in two lessons by 60 cubic inches. In one additional week I could dismiss him with a full sonorous man's voice, in place of the uncertain child's squeak with which he came to me. It is no exaggeration to say that this young man left me with a _new_ voice, and if people had heard him when he first came to me, behind a screen, and again after the last lesson, they would certainly not have believed that they were listening to the same person. What Mr. X and his friends think of his case may be seen from the following letter which he wrote me on July 6th, 1880:--"Now that a week has passed since the last lesson I had from you, I write to bear testimony to the wonderful benefit to my voice obtained through the very short course I took. My friends are quite astonished at the marked difference, and I beg you will accept my most sincere thanks," &c.

Many similar cases might be mentioned, but the one just quoted is sufficient, and I will sum the matter up with a few remarks which Mr. Lennox Browne made as chairman at my lecture at the Aldersgate Street Literary Institution, on October 9th, 1880. He then said that, in his medical experience, he found that persons who suffered from their voices generally owed their ailments to bad habits of using the voice, and not to any defect in the larynx or resonance chamber. In several cases lately he had sent such patients to Herr Behnke, who had given them lessons in correct breathing, and who had thereby, and without any medicine, galvanism, or other aid, restored their voices in a remarkably short time.

From what has been said above about midriff and rib breathing _versus_ collar-bone breathing, the folly of tight-lacing, or, indeed, of in any way interfering with the freedom of the waist, will be at once apparent. We pride ourselves upon our civilization; we make a boast of living in the age of science; physiology is now taught, or at least talked of, in almost every school; the laws of health are proclaimed in lectures and lessons innumerable all over the country, and we laugh at barbarous customs of other nations, such, for instance, as that of Chinese women preventing the growth of their feet by forcing them into boots of only half their proper size. And yet our ladies wear instruments of torture called corsets, altering the shape of their bodies, and positively driving the lower ribs _into the lungs_! Now which folly is the greater--that of doubling up the toes, or of crippling the body in its most vital parts? Let ladies answer the question, and let them further most solemnly consider that the girls of to-day are the mothers of to-morrow, and that upon the measure of their own health and strength depends the well-being of coming generations.

It is only fair to add, that if the practice of interfering with the freedom of the waist is reprehensible in the case of ladies, it is, in one sense, still more so in the case of the male sex, because, as has been shown before, men depend more for their breathing upon the action of the abdominal muscle than women. They should, therefore, neither wear tight-fitting vests, nor suspend their pantaloons by means of waistbands, belts, or buckles. Loose garments and braces are the proper thing, though the latter are commonly, but erroneously, considered to be injurious. _Abdominal_ belts may be worn with advantage by persons of either sex requiring their support; but these are very different from stays or waist-bands. I find that an enterprising firm is advertising corsets for gentlemen (!), and a woodcut may be seen in some papers representing a young Adonis laced up in regular ladies' fashion, so that, if it were not for his luxurious moustache, one would certainly take the drawing to be meant for a woman. It is almost impossible to imagine that a man could ever make such a fool of himself; on the other hand, it is clear that these advertisements would not continue to appear if they did not bring customers. But these poor creatures do not deserve to be called men, and I am sincerely sorry for them.

With regard to the question whether inspiration should take place through the mouth or through the nostrils, I must enter my most decided protest against making it a practice to inhale through the mouth. There are, of course, occasions when this is unavoidable, as, for instance, where the singer has rapidly to take what is called a "half breath." But complete inflation, or, "full breath," is not the work of a moment; it takes time, and must be done gradually, steadily, and without the slightest interruption. This should _always_ be done through the nostrils. The mouth was never intended for breathing, while the nose is specially and admirably adapted for this purpose. Not only can the lungs be well and quickly filled through this channel, but it is so cunningly devised that it acts at the same time as a "respirator," both purifying and warming the air before it touches the more delicate parts of the vocal organ. On the other hand, when inhaled through the mouth, the air carries with it, sometimes right into the voicebox, dust and other impurities, and its temperature is not materially altered. The consequence is that the throat and voicebox, when heated by singing or talking, or by hot rooms, are often exposed to cold, raw, and foggy winter air, and serious derangements of the respiratory organs are the natural consequence. If, moreover, this pernicious habit of breathing be once contracted, we shall soon also sleep with open mouths, thus parching our throats, and sowing the seeds of many a serious disorder.

On this point I quote a few lines from Dr. Louis Elsberg,[F] professor of laryngology in the University of New York: "The natural mode of quiet breathing is through the nose; mouth-breathing is an acquirement. A new-born infant would choke to death if you closed its nose; it does not immediately know how to get air into the lungs through the mouth until after, by depressing the tongue, you have once made a passage for it."

George Catlin, the celebrated traveller among American Indians, became so thoroughly convinced that the difference between the healthy condition and physical perfection of these people in their primitive state, especially their sound teeth and good lungs, and the deplorable mortality, the numerous diseases and deformities in _civilized_ communities, is mainly due to the habit, common among the latter, of breathing through the mouth, especially during sleep, that he wrote a book entitled "Malrespiration and its Effects upon the Enjoyment and Life of Man." In this book he says, "If I were to endeavour to bequeath to posterity the most important motto which human language can convey, it should be in three words, 'Shut your mouth.' In the social transactions of life this might have its beneficial results as the most friendly cautionary advice, or be received as the grossest of insults; but where I would print and engrave it, in every nursery and on every bedpost in the universe, its meaning could not be mistaken, and obeyed, its importance would soon be realized."

He also says, "It is one of the misfortunes of civilization that it has too many amusing and exciting things for the mouth to say, and too many delicious things for it to taste, to allow of its being closed during the day. The mouth therefore has too little reserve for the protection of its natural purity of expression, and too much exposure for the protection of its garniture; but, _do keep your mouth shut_ when you _read_, when you _write_, when you _listen_, when you _are in pain_, when you are _walking_, when you are _running_, when you are _riding_, and _by all means when you are angry_! There is _no person_ but who will find and acknowledge _improvement_ in _health_ and _enjoyment_ from even a temporary attention to this advice."

Again he says, "There is a proverb, as old and unchangeable as their hills, amongst North American Indians, 'My son, if thou wouldst be wise, open first thy eyes; thy ears next, and last of all thy mouth, that thy words may be words of wisdom, and give no advantage to thine adversary.' This might be adopted with good effect in _civilized_ life; he who would _strictly adhere_ to it would be sure to reap its benefits in his _waking_ hours, and would _soon find_ the habit running into his hours of _rest_, into which he would _calmly_ enter; dismissing the nervous anxieties of the day, as he firmly closed his teeth and his lips, only to be opened _after_ his eyes and his ears in the morning, the rest of _such_ sleep would bear him daily and hourly proof of its value."

Catlin regards the habit of sleeping with the mouth open the most pernicious of _all bad habits_. The horrors of nightmare and snoring are, according to him, but the _least_ of its evil effects. He thinks "for the greater portion of the thousands and tens of thousands of persons suffering with weakness of lungs, with bronchitis, asthma, indigestion, and other affections of the digestive and respiratory organs," the correction of this habit is a _panacea_ for their ills!

He insists that "_mothers_ should be looked to as the first and principal _correctors_ of this most destructive of human habits; ... and the united and simultaneous efforts of the civilized world should be exerted in the overthrow of a monster so destructive to the good looks and life of man. Every physician should advise his patients, and every boarding-school in existence and every hospital should have its surgeon or matron, and every regiment its officer, to make their nightly and hourly 'rounds,' to force a _stop_ to so unnatural, disgusting, and dangerous a habit! Under the working of such a system, mothers guarding and helping the helpless, schoolmasters their scholars, hospital surgeons their patients, generals their soldiers, and the rest of the world protecting themselves, a few years would show the glorious results in the bills of mortality, and the next generation would be a _regeneration_ of the human race."
