Peptidoglycan Layer

Famous quotes containing the word layer:

    After a few months’ acquaintance with European “coffee,” one’s mind weakens, and his faith with it, and he begins to wonder if the rich beverage of home, with its clotted layer of yellow cream on top of it, is not a mere dream after all, and a thing which never existed.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
