1919 publication on Stuttering (alalia syllabaris) or stammering (alalia literalis or anarthria literalis), a speech disorder in which the flow of speech is disrupted by involuntary repetitions and prolongations of sounds, syllables, words or phrases, and involuntary silent pauses or blocks in which the stutterer is unable to produce sounds. "Considerably more than a third of a century has elapsed since I purchased my first book on stammering. I still have that quaint little book made up in its typically English style with small pages, small type and yellow paper back-the work of an English author whose obtuse and half-baked theories certainly lent no clarity to the stammerer's understanding of his trouble. Since that first purchase my library of books on stammering has grown until it is perhaps the largest individual collection in the world. I have read these books-many of them several times, pondered over the obscurities in some, smiled at the absurdities in others and benefited by the truths in a few. Yet, with all their profound explanations of theories and their verbose defense of hopelessly unscientific methods, the stammerer would be disappointed indeed, should he attempt to find in the entire collection a practical and understandable discussion of his trouble.
