RULE XIII.—PRONOUNS.
When a Pronoun has two or more antecedents connected by or or nor, it must agree with them singly, and not as if taken together: as; "James or John will favour us with his company."—"Neither wealth nor honour can secure the happiness of its votaries."
"What virtue or what mental grace,
But men unqualified and base
Will boast it their possession?"—Cowper, on Friendship.
