“Thus shall mankind his guardian care engage,
    The promised father of a future age.”—­Pope.

But possibly such examples may be otherwise explained on the principle of ellipsis; as, [He being] “the promised father,” &c.  “As [he was] an author,” &c.  “As [you are] an instructer.”

OBS. 11.—­When a noun or pronoun is repeated for the sake of emphasis, or for the adding of an epithet, the word which is repeated may properly be said to be in apposition with that which is first introduced; or, if not, the repetition itself implies sameness of case:  as, “They have forsaken me, the fountain of living waters, and hewed them out cisterns, broken cisterns, that can hold no water.”—­Jer., ii, 13.

   “I find the total of their hopes and fears
    Dreams, empty dreams.”—­Cowper’s Task, p. 71.

OBS. 12.—­A noun is sometimes put, as it were, in apposition to a sentence; being used (perhaps elliptically) to sum up the whole idea in one emphatic word, or short phrase.  But, in such instances, the noun can seldom be said to have any positive relation that may determine its case; and, if alone, it will of course be in the nominative, by reason of its independence.  Examples:  “He permitted me to consult his library—­a kindness which I shall not forget.”—­W.  Allen’s Gram., p. 148.  “I have offended reputation—­a most unnoble swerving.”—­Shakspeare.  “I want a hero,—­an uncommon want.”—­Byron.  “Lopez took up the sonnet, and after reading it several times, frankly acknowledged that he did not understand it himself; a discovery which the poet probably never made before.”—­Campbell’s Rhet., p. 280.

   “In Christian hearts O for a pagan zeal! 
    A needful, but opprobrious prayer!”—­Young, N. ix, l. 995.

    “Great standing miracle, that Heav’n assign’d
    Its only thinking thing this turn of mind.”—­Pope.

OBS. 13.—­A distributive term in the singular number, is frequently construed in apposition with a comprehensive plural; as, “They reap vanity, every one with his neighbour.”—­Bible.  “Go ye every man unto his city.”—­Ibid. So likewise with two or more singular nouns which are taken conjointly; as, “The Son and Spirit have each his proper office.”—­Butler’s Analogy, p. 163.  And sometimes a plural word is emphatically put after a series of particulars comprehended under it; as, “Ambition, interest, glory, all concurred.”—­Letters on Chivalry, p. 11.  “Royalists, republicans, churchmen, sectaries, courtiers, patriots, all parties concurred in the illusion.”—­Hume’s History, Vol. viii, p. 73.  The foregoing examples are plain, but similar expressions sometimes
