Famous quotes containing the words tests, latent and/or tuberculosis:

    From a hasty glance through the various tests I figure it out that I would be classified in Group B, indicating “Low Average Ability,” reserved usually for those just learning to speak the English Language and preparing for a career of holding a spike while another man hits it.
    Robert Benchley (1889–1945)

    Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?
    Jean Genet (1910–1986)

    With sighs more lunar than bronchial,
    Howbeit eluding fallopian diagnosis,
    She simpers into the tribal library and reads
    That Keats died of tuberculosis . . .
    Allen Tate (1899–1979)
