several forms, any one of which will fall into one of four phases:

(1)--Simple Phase
(2)--Advanced Phase
(3)--Mental Phase
(4)--Compound Phase

Simple stuttering can be said to be a purely physical form of the
difficulty. The Advanced Phase marks the stage of further progress
where the trouble passes from the purely physical state into a
condition that may be known as Mental-Physical. The distinctly
Mental Phase is marked by symptoms indicating a mental cause for
the trouble, the disorder usually having passed into this form
from the simple or advanced stages of the malady. Stuttering may
be combined with stammering in which case the condition represents
the Compound Phase of the trouble.

CHOREATIC STUTTERING: This originates in an attack of Acute Chorea
or St. Vitus Dance, which leaves the sufferer in a condition where
involuntary and spasmodic muscular contractions, especially of the
face, have become an established habit. This breaks up the speech
in a manner somewhat similar to ordinary stuttering. Also known as
"Tic Speech."

SPASTIC SPEECH: This is often the result of infantile cerebral
palsy, the characteristic symptom of the trouble being intense
over-exertion, continued throughout a sentence, the syllables
being equal in length and very laboriously enunciated. In spastic
speech, there is present a noticeable hyper-tonicity of the nerve
fibers actuating the muscles used in speaking as well as marked
