es, El. of Crit._, ii, 268. "_From_ which
there are but two _exceptions_, both of them rare."--_Ib._, ii. 89. "_To_
the rule that fixes the pause after the fifth portion, there is one
_exception_, and no more."--_Ib._, ii, 84. "No _exception_ can be taken
_to_ the justness of the figure."--_Ib._, ii, 37. "Originally there was no
_exception_ from the rule."--_Lowth's Gram._, p. 58. "_From_ this rule
there is mostly an _exception_."--_Murray's Gram._, i, 269. "But _to_ this
rule there are many _exceptions._"--_Ib._, i. 240. "They are not to be
regarded as exceptions _from_ the rule,"--_Campbell's Rhet._, p. 363.

OBS. 18.--After correcting the example. "He _knows_ nothing _on_ [of] it,"
Churchill remarks, "There seems to be a strange perverseness among the
_London vulgar_ in perpetually substituting _on_ for _of_, and _of_ for
_on_."--_New Gram._, p. 345. And among the expressions which Campbell
censures under the name of _vulgarism_, are the following: "'Tis my humble
request you will be particular in speaking _to_ the following
points."--_Guardian_, No. 57. "The preposition ought to have been _on_.
Precisely of the same stamp is the _on't_ for _of it_, so much used by one
class of writers."--_Philosophy of Rhet._, p. 217. So far as I have
observed, the use of _of_ for _on_ has never been frequent; and that of
_on_ for _of_, or _on't_ for _of it_, though it may never have been a
polite custom, is now a manifest _archaism_, or imitation of ancient usage.
"And so my young Master, whatever comes _on't_, must have a Wife look'd out
for him."--_Locke, on Ed._, p. 378. In Saxon, _on_ was put for more than
half a dozen of our present prepositions. The difference between _of_ and
_on_ or _upon_, appears in general to be obvious enough; and yet there are
some phrases in which it is not easy to determine which of these words
ought to be preferred: as, "Many things they cannot _lay hold on_ at
once."--HOOKER: _Joh. Dict._ "Uzzah put forth his hand to the ark of God,
and _took hold of_ it."--2 SAM.: _ib._ "Rather thou shouldst _lay hold
upon_ him."--BEN JONSON: _ib._ "Let them find courage to _lay hold on_ the
occasion."--MILTON: _ib._ "The hand is fitted to _lay hold of_
objects."--RAY: _ib._ "My soul _took hold on_ thee."--ADDISON: _ib._ "To
_lay hold of_ this safe, this only method of cure."--ATTERBURY: _ib._ "And
_give_ fortune no more _hold_ of him."--DRYDEN: _ib._ "And his laws _take_
the surest _hold of_ us."--TILLOTSON: _ib._
