Note: To the meaning of by, as denoting means or agency, belong, more or less closely, most of the following uses of the word:
(a) It points out the author and producer; as, ``Waverley'', a novel by Sir W.Scott; a statue by Canova; a sonata by Beethoven.
(b) In an oath or adjuration, it indicates the being or thing appealed to as sanction; as, I affirm to you by all that is sacred; he swears by his faith as a Christian; no, by Heaven.

Note: In boxing the compass, by indicates a pint nearer to, or towards, the next cardinal point; as, north by east, i.e., a point towards the east from the north; northeast by east, i.e., on point nearer the east than northeast is. Note: With is used instead of by before the instrument with which anything is done; as, to beat one with a stick; the board was fastened by the carpenter with nails. But there are many words which may be regarded as means or processes, or, figuratively, as instruments; and whether with or by shall be used with them is a matter of arbitrary, and often, of unsettled usage; as, to a reduce a town by famine; to consume stubble with fire; he gained his purpose by flattery; he entertained them with a story; he distressed us with or by a recital of his sufferings. see {With}. {By all means}, most assuredly; without fail; certainly. {By and by}.

(b) Immediately; at once. [Obs.] ``When . . . persecution ariseth because of the word, by and by he is offended.'' --Matt. xiii. 21.
(c) Presently; pretty soon; before long. Note: In this phrase, by seems to be used in the sense of nearness in time, and to be repeated for the sake of emphasis, and thus to be equivalent to ``soon, and soon,'' that is instantly; hence, -- less emphatically, -- pretty soon, presently. {By one's self}, with only one's self near; alone; solitary. {By the bye}. See under {Bye}. {By the head} (Naut.), having the bows lower than the stern; -- said of a vessel when her head is lower in the water than her stern.

Note: The common phrase good-by is equivalent to farewell, and would be better written good-bye, as it is a corruption of God be with you (b'w'ye).
