In all varieties and forms of stammering-stuttering all the vocal organs can be blamed, and have, in each case, to be reformed and improved. In the majority of cases we find some traces of the organic peculiarities aimed at by authors, even if their influence is doubtful. Respiratory trouble is at the bottom of every case. The internal organs, and the tongue, the lips and jaws are to some extent in an abnormal condition, and suffer a convulsive spasm; they have to be treated, strengthened and made flexible. The nerve-function of the organs of speech is also disturbed. We notice in the majority of cases, to a certain degree, organic weakness, nervousness, lack of will-power, and above all, disregard of all natural rules and ignorance of the use and natural functions of the organs of speech. As to prognosis, I will say that all stoppages in speech, accompanied by spasms, sometimes hardly perceptible, and which are not the result of paralysis or lesion, may be classified as stammering-stuttering, and can always be cured, whatever may be their origin or cause, or their intensity, and that it is only a question of time and perseverance even for the most stubborn cases. The treatment of stammering-stuttering, which does not comport any operation nor drugs, is purely educational. It consists in remedying the defect and teaching properly the science of speech. Still, I think, that in many cases a strict attention ought to be paid to hygienic measures; some medical care and prescription would help the patient and the instructor. In the actual condition of things no regular practicing physician can afford to devote his ability and time to the treatment of speech defects. But doctors have to study the infirmity, to know that it can be cured, that it is an interesting and complex disease, in the treatment of which the progress of medical science can bring a revolution. Physicians the world over having wholly neglected to consider that question, the result has been to leave it in the hands of incompetent persons. In principle the question of speech impediments cannot be separated from medicine. Physicians cannot ignore an infirmity in which the organism itself is undoubtedly involved, at times in a very intricate manner and to a considerable extent. Every true physician feels that he has a sacred mission—to alleviate suffering; the tortures of a large class of people partially deprived of the faculty of speech are well worth his care and attention. Medical students ought to be provided with the means of becoming versed in an affection offering such a large field for study and work, where so much light is needed, and where the prospects of discovery and improvement from a scientific and medical standpoint are so legitimate. The family physician, often consulted, will do good work in advising his clients to try and get rid of such a terrible affliction, to be cured without delay, and in preventing them from falling into the hands of quacks.
