the only subjects of the
verbs which follow them: as, "The Lord will show _who are_ his, and _who
is_ holy."--_Numbers_, xvi, 5. "Hardly is there any person, but _who_, on
such occasions, _is disposed_ to be serious."--_Blair's Rhet._, p. 469.
"Much of the merit of Mr. Addison's Cato depends upon that moral turn of
thought _which distinguishes_ it."--_Ib._, 469. "Admit not a single word
but _what is_ necessary."--_Ib._, p. 313. "The pleader must say nothing but
_what is_ true; and, at the same time, he must avoid saying any thing _that
will hurt_ his cause."--_Ib._, 313. "I proceed to mention such _as appear_
to me most material."--_Ib._, p. 125. After _but_ or _than_, there is
sometimes an ellipsis of the relative, and perhaps also of the antecedent;
as, "There is no heart _but must feel_ them."--_Blair's Rhet._, p. 469.
"There is no one _but must be_ sensible of the extravagance."--_Ib._, p.
479. "Since we may date from it a more general and a more concerted
opposition to France _than there had been_ before."--_Bolingbroke, on
Hist._, p. 213. That is, "than _what_ there had been before;"--or, "than
_any opposition which_ there had been before." "John has more fruit _than
can be gathered_ in a week."--_O. B. Peirce's Gram._, pp. 196 and 331. I
suppose this sentence to mean, "John has more fruit than _what_ can be
gathered in a week." But the author of it denies that it is elliptical, and
seems to suppose that _can be gathered_ agrees with _John_. Part of his
comment stands thus: "The above sentence--'John has more fruit than can be
gathered in a week'--in every respect full and _perfect_--must, to be
_grammatical_! according to _all_ the 'old theories,' stand, John has more
fruit than _that fruit is which, or which fruit_ can be gathered in a
week!!!"--_Ib._, 331. What shall be done with the headlong critic who thus
mistakes exclamation points for arguments, and multiplies his confidence in
proportion to his fallacies and errors?

OBS. 19.--In a question, the nominative _I_ or _thou_ put after the verb,
controls the agreement, in preference to the interrogative _who, which_, or
_what_, put before it; as, "_Who am I? What am I? Who art thou? What art
thou?_" And, by analogy, this seems to be the case with all plurals; as,
"_Who are we? Who are you? Who are they? What are these_?" But sometimes
the interrogative pronoun is the only nominative used; and then the verb,
whether singular or plural, must agree with this nominat
