In Mufic1 Semi has three' feveral Ufages: Firft, when
added to a Note, it exprefles a Diminution of Half its
Value, as Semi l1rtve, &c. which See. Secondly, when
added to the Name of an Interval, it exprefes a Diminu-
tion, not of Half, but of a minor Half-tone, or four
Commas in the whole Compafs. Thirdly, it iometimes
fignifies an Imperfetion. Thus Semicircolo or Circolo-
mezzo, rignifes an imperfe~ l Circle, which is the Mark
of imperfed Time, that is, of double Time; whereas,
the Circle, being a CharaEter of Perfecion, marks triple

it did not avail the teaching, that there was no other

SEMI-COLON, in Grammar, one of the Points or Stops,
ufed to diflinguilh the feveral Members of Sentences from
each other. See SENTENCE and POINT. The Mark or
Charader of the Semi-colon is (;) It has its Name, as
having a fomewhat lefs Efae& than a Colon, or as de-
manding a fhorter Paufe. The Ufe of the Semi-colon,
the Grammarians generally fay, is, To mark a Senfe lels
compleat than the Colon, and more complear than the
Comma; but this only conveys a very obfcure Idea. In
effe&, the precife Ufe of the Semi-colon, or what it is
diffinguiflies it from the Colon, is a Thing very little
known in the World. Our beft Authors feen to ufe them
promifcuoufly. See COLON.
Mr. Ward, we believe, is the firfi (and he in the pre-
fent Year i7p4) who ever lettled the precifr Ufe of rhe
Semi-colon. His Obfervation is, Thar the Semi.colon is
properly rfed to diflinguf  the conjunf7 AMembers of Sen.
tences: Now, by a conjunfl Member of a Sentece, he
means, fuch a one as contains at leaft two fimple Members.
See SENT EN C E. Whenever, then, a Sentence can be divided
into leveral Members of the fame Degree; which are
jgain divifible into other fimple Members, the former arc
to be fepmrated by a Semi-colon. For an Inflance: it
