"Lacuna" Quotes from Famous Books



... no satisfactory explanation to offer. He may have set his own judgment above Homer—a most unlikely hypothesis: he may have been consistently following, in the framework of his story, some original now lost to us: there may be more, and longer, lacunae in the text than any editors have ventured to indicate: but, whatever theory we adopt, it must ...

The blood, which is a non-corpuscular fluid, is propelled ...

... for Brown, Williams, and Pennsylvania. Princeton won by her brilliant work in the classics and biology. Firsts were made by Bentley, who did the 220 lines of Homer in 29-3/5 minutes, scanned 100 Alcaics from Horace in 62 seconds flat, and hurdled over nine doubtful readings and seven lacunae in the text of Aristotle's 'Poetics' in 17-1/2 minutes. Two firsts went to Ramsdell, who made only two errors in Protective Colouration and one error in explaining the ...

... passage of instruments, or form the variety of stricture known as spasmodic. The urethra is lined by a delicate mucous membrane presenting longitudinal folds, which become obliterated by distention; and its entire surface is numerously studded with the orifices of mucous cells (lacunae), one of which, larger than the rest, appears on the upper side of the canal near the meatus. Some of these lacunae are nearly an inch long, and all of them open in an oblique direction forwards. Instruments having very narrow ...

... had belonged to Nicholas Perotti, Archbishop of Sipontum or Manfredonia, at the end of the fifteenth century, and who, notwithstanding his assertions to the contrary, was perhaps either the author of them or altered them very materially. They appear in the MSS. in a mutilated condition; and the lacunae have been filled up according to the fancy of the successive Editors of the Fables. Those inserted in Gail's edition have in ...

... beguile the reader and blind him, at first, to the many discrepancies and incoherences with which the text, as we have it, is marred. The more one concentrates upon this author, the more apparent these faults become and the more one regrets the lacunae in the text. Notwithstanding numerous articles which deal with this work, some from the pens of the most profound scholars, its author is still shrouded in the mists of uncertainty and conjecture. He is as impersonal as Shakespeare, as aloof as Flaubert, ...

... unknown scribe had celebrated his exploits, existed about the middle of the VIIth century before our era in the Royal Library at Nineveh; they had been transcribed by order of Assur-banipal from a more ancient copy, and the fragments of them which have come down to us, in spite of their lacunae, enable us to restore the original text, if not in its entirety, at least in regard to the succession of events. They were divided into twelve episodes corresponding with the twelve divisions of the year, and the ancient Babylonian author was guided in his choice of ...

... inquisitive, unsettled genius, no less preoccupied with the marvellous intelligence of some Brazilian parrot, than with the sad obstinacy of some Bishop of Worcester? Here is eternal freshness of conviction and ardour for reform; great keenness of perception in spots, and in other spots lacunae and impulsive judgments; distrust of tradition, of words, of constructive argument; horror of vested interests and of their smooth defenders; a love of navigating alone and exploring for oneself even the coasts already well charted by others. Here is romanticism united ...

... procedure was that of a dilettante; the patient, assiduous labor demanded for the successful promotion of the mission of natural investigation was not his forte. His strength lay in the postulation of problems, the stimulation and direction of inquiry, the discovery of lacunae and the throwing out of suggestions; and many ideas incidentally thrown off by him surprise us by their ingenious anticipations of later discoveries. The greatest defect in his theory was his complete failure to recognize the services promised by mathematics to ...
