the
true characteristics of a relative pronoun, it is proper to refer the word
to that class. But when a clause or a sentence is the antecedent, it is
better to consider the _as_ a conjunction, and to supply the pronoun _it_,
if the writer has not used it; as, "He is angry, _as [it] appears_ by this
letter." Horne Tooke says, "The truth is, that AS is _also an article_; and
(however and whenever used in English) means the same as _It_, or _That_,
or _Which_."--_Diversions of Purley_, Vol. i, p. 223. But what definition
he would give to _"an article_," does not appear.

OBS. 10.--In some examples, it seems questionable whether _as_ ought to be
reckoned a pronoun, or ought rather to be parsed as a conjunction after
which a nominative is understood; as, "He then read the conditions _as
follow_."--"The conditions are _as follow_."--_Nutting's Gram._, p. 106.
"The principal evidences on which this assertion is grounded, are _as
follow_."--_Gurney's Essays_, p. 166. "The Quiescent verbs are _as
follow_."--_Pike's Heb. Lex._, p. 184. "The other numbers are duplications
of these, and proceed _as follow_"--_Dr. Murray's Hist. of Lang._, Vol. ii,
p. 35. "The most eminent of the kennel are bloodhounds, which lead the van,
and are _as follow_."--_Steele, Tattler_, No. 62. "His words are _as
follow_."--_Spect._, No. 62. "The words are _as follow_."--_Addison,
Spect._, No. 513. "The objections that are raised against it as a tragedy,
are _as follow_."--_Gay, Pref. to What d' ye call it_. "The particulars are
_as follow_."--_Bucke's Gram._, p. 93. "The principal interjections in
English are _as follow_."--_Ward's Gram._, p. 81. In all these instances,
one may suppose the final clause to mean, "as _they here_ follow;"--or,
supposing _as_ to be a pronoun, one may conceive it to mean, "_such_ as
follow." But some critical writers, it appears, prefer the singular verb,
"_as follows_" Hear Campbell: "When a verb is used _impersonally_, it ought
undoubtedly to be in the singular number, whether the neuter pronoun be
expressed or understood: and when no nominative in the sentence can
regularly be construed with the verb, it ought to be considered as
impersonal. For this reason, analogy as well as usage _favour_ [say
_favours_] this mode of expression, 'The conditions of the agreement
were _as follows_;' and not '_as follow_.' A few late writers have
inconsiderately adopted this last form through a mistake of the
construction. For the same rea
