arc held together by the pitch or key and the modulation of the voice,
and the middle part, the group of examples, is held together in a
different key by being set in the background, as being illustrative or
probative. "Why, all these Irish bulls are Greek,--every one of them.
Take the Irishman carrying around a brick as a specimen of the house he
had to sell; take the Irishman who shut his eyes, and looked into the
glass to see how he would look when he was dead; take the Irishman that
bought a crow, alleging that crows were reported to live two hundred
years, and he meant to set out and try it. Well, those are all Greek. A
score or more of them, of the parallel character, come from Athens."

The speaker should cultivate a quick sensitiveness as to close unity
and slight diversity, as to what is principal and what is subordinate,
as to what is in the direct, main line of thought, and what is by the
way, casual, or merely a connecting link. This sense of proportion, of
close or remote relation, of directness and indirectness, the feeling
for perspective, so-called, can be acquired only by continued practice,
for sharpening the faculty of apprehension and appreciation. It is
usually the last attainment in the student's work, but the neglect of
it may result in a confirmed habit of monotony. The term transition is
commonly used to denote a passing from one to another of the main
divisions of the discourse. The making of this transition, though often
neglected, is not difficult. The finishing of one part and the making
of a new beginning on the next, usually with some change of standing
position, as well as of voice, has an obvious method. The slighter
transition, or variation, within a main division, and the avoidance of
the slight transition where none should be made, require the keener,
quicker insight.
