Famous quotes containing the words digit and/or significant:

    Bless my soul, Sir, will you Britons not credit that an American can be a gentleman, & have read the Waverly Novels, tho every digit may have been in the tar-bucket?
    Herman Melville (1819–1891)

    Priests and physicians should never look one another in the face. They have no common ground, nor is there any to mediate between them. When the one comes, the other goes. They could not come together without laughter, or a significant silence, for the one’s profession is a satire on the other’s, and either’s success would be the other’s failure.
    Henry David Thoreau (1817–1862)
