of his system — the initial inspiration."
Should one prefer to regard Colombat as the victim
of a series of unfortunate coincidences, he must never-
theless admit that his " discoveries" were anticipated.
Rhythm was employed by Thelwall as early as
1801, which was long before Colombat entered the
field. Thelwall says of his system:l
"From one simple and original principle (whose existence
and operation, I trust, are sufficiently demonstrated by the
series of experiments regularly exhibited) I trace the fundamen-
tal and physical distinctions of heavy and light syllables; and
from the unavoidable alternations of these (or of pauses of the
voice during the actions by which they should be produced) I
demonstrate the formation of those simple cadences of com-
mon and triple measure, out of which arise all the beauties of
rhythmus, and all the facilities of fluent and harmonious ut-
terance. From an injudicious application of undisciplined vo-
lition to this physical action, I endeavour to account for all
the gradations of harsh, ungraceful, and interruptive delivery;
and from inconsiderate attempts to violate this primary law,
all the customary impediments of speech."
"Yet I could not but observe and feel, how much the prin-
ciple of physiological rhythmus, and the conformity of the
volition with its dictates, mitigated the labour of pectoral
exertion, and contributed to a healthful and agreeable action
of the lungs."2
