A stutterer, whose tongue is running away with him, owing to an insufficiency of ballast, must take in enough (inspire sufficiently) to bring him back to his point of gravitation. _His tongue is in a loose state of elevation, in which position the air is constantly streaming out (expiring) from beneath the same._ He must _lower_ it to have _his_ balance restored, as in so doing the air will stream in over and above the tongue until the equilibrium has been restored. In other words, the person who is thus agitated must calm himself, he must relax from an overstrain in either one direction or the other. The diaphragm, holding the balance of power, will be found to be in as uncontrollable a condition as the tongue, _with which it always acts in unison_. In restoring the tongue to a normal condition we restore the diaphragm to a normal condition. The institutions for the cure of stuttering, stammering, and intermediate stages of the same trouble, attempt to bring about a state of restoration of the disturbed balance by means arrived at through experience. The real cause being unknown, the remedies must necessarily be restricted. If persons thus afflicted will take their own cases in hand and treat them in conformity with the precepts here laid down, the chances are in favor of their being cured where no other remedy had been of any avail. As the preceding remarks have been made from the point of view of an English-speaking person, the standpoint of a German being diametrically opposite, the same must all be reversed to fit the case of a German, in so far as locality is concerned. _For stammering, the tongue of a German is closely wedged in, in the direction of the roof of the mouth; for stuttering, it is loosely pointing downward._ This is owing to the fact that a German inspires from under and beneath, and expires from over and above, his tongue; just the reverse of the manner in which this is done by an English-speaking person. In order to efficiently cure the trouble of stuttering, it is necessary that the act of breathing and sound-production should be closely studied with every separate nationality, as these processes differ with all nationalities; this difference being very pronounced as between Germans and Anglo-Saxons. For an American to go to Germany, therefore, to be cured of this trouble, is as false a step as for a German to go to the United States or England for this purpose. While I have in the preceding endeavored to give an account of the general causes which result in stuttering, I have not touched upon such special causes as are directly connected with the character and origin of vocal sounds; the explanation of which must be postponed to a future period.
