at_, and _thrive_, of the latter.

[297] In the following example, there is a different phraseology, which
seems not so well suited to the sense: "But we _must be aware_ of
imagining, that we render style strong and expressive, by a constant and
multiplied use of epithets"--_Blair's Rhet._, p. 287. Here, in stead of
"_be aware_," the author should have said, "_beware_," or "_be ware_;" that
is, be _wary_, or _cautious_; for _aware_ means _apprised_, or _informed_,
a sense very different from the other.

[298] Dr. Crombie contends that _must_ and _ought_ are used only in the
present tense. (See his _Treatise_, p. 204.) In this he is wrong,
especially with regard to the latter word. Lennie, and his copyist
Bullions, adopt the same notion; but Murray, and many others, suppose them
to "have both a present and [a] past signification."

[299] Dr. Crombie says, "This Verb, as an auxiliary, is _inflexible_; thus
we say, 'he _will_ go;' and 'he _wills to_ go.'"--_Treatise on Etym. and
Syntax_, p. 203. He should have confined his remarks to the _familiar
style_, in which all the auxiliaries, except _do, be_, and _have_, are
inflexible. For, in the solemn style, we do not say, "Thou _will_ go," but,
"Thou _wilt_ go."

[300] "HAD-I-WIST. A proverbial expression, _Oh_ that I had known.
_Gower_."--_Chalmers's Dict._, also _Webster's_. In this phrase, which is
here needlessly compounded, and not very properly explained, we see _wist_
used as a perfect participle. But the word is obsolete. "_Had I wist_," is
therefore an obsolete phrase, meaning. If I had known, or, "_O_ that I had
known."

[301] That is, passive verbs, as well as others, have three participles for
each; so that, from one active-transitive root, there come _six_
participles--three active, and three passive. Those numerous grammarians
who, like Lindley Murray, make passive verbs a distinct class, for the most
part, very properly state the participles of a _verb_ to be "_three_;" but,
to represent the two voices as modifications of one species of verbs, and
then say, "The Participles are _three_," as many recent writers do, is
manifestly absurd: because _two threes should be six_. Thus, for example,
Dr. Bullions: "In English [,] the _transitive_ verb has always _two
voices_, the Active and [the] Passive."--_Prin. of E. Gram._, p. 33. "The
Participles are _three_, [:] the Present, the _Perfect_, and the _Compound
Perfect_."--_Ib._, p. 57. Again: "_Transitive_ verbs ha
