tings at certain places and times, _as_ may best suit
the convenience of _such, who_ may be most particularly concerned in
them."--_Barclay's Works_, Vol. i, p. 495. "Which, no doubt, will be found
obligatory upon all _such, who_ have a sense and feeling of the mind of the
Spirit."--_Ib._, i, p. 578. "Condemning or removing _such_ things, _which_
in themselves are evil."--_Ib._, i, p. 511. In these citations, not only
are _who_ and _which_ improperly used for _as_, but the _commas_ before
them are also improper, because the relatives are intended to be taken in a
restrictive sense. "If there be _such that_ walk disorderly now."--_Ib._,
i, p. 488. Here _that_ ought to be _as_; or else _such_ ought to be
_persons_, or _those._ "When such virtues, _as which_ still accompany the
truth, are necessarily supposed to be wanting."--_Ib._, i, p. 502. Here
_which_, and the comma before _as_, should both be expunged. "I shall raise
in their minds the same course of thought _as_ has taken possession of my
own."--_Duncan's Logic_, p. 61. "The pronoun must be in the same case _as_
the antecedent would be _in_, if substituted for it."--_Murray's Gram._, p.
181. "The verb must therefore have the same construction _as_ it has in the
following sentence."--_Murray's Key_, p. 190. Here _as_ is exactly
equivalent to the relative _that_, and either may be used with equal
propriety. We cannot avoid the conclusion, therefore, that, as the latter
word is sometimes a conjunction and sometimes a pronoun, so is the former.

OBS. 23.--The relatives _that_ and _as_ have this peculiarity; that, unlike
_whom_ and _which_, they never follow the word on which their case depends;
nor indeed can any simple relative be so placed, except it be governed by a
preposition or an infinitive. Thus, it is said, (John, xiii, 29th,) "Buy
those things _that_ we have need _of_;" so we may say, "Buy such things
_as_ we have need of." But we cannot say, "Buy those things _of that_ we
have need;" or, "Buy such things _of as_ we have need." Though we may say,
"Buy those things _of which_ we have need," as well as, "Buy those things
_which_ we have need _of_;" or, "Admit those persons of whom we have need,"
as well as, "Admit those persons _whom_ we have need _of._" By this it
appears that _that_ and _as_ have a closer connexion with their antecedents
than the other relatives require: a circumstance worthy to have been better
remembered by some critics. "Again, _that_ and _as_
