From an advertisement for a potion produced by Guyot: “Everyone knows that bad microbes are the cause of almost all of our major diseases: tuberculosis, influenza, diphtheria, typhoid fever, meningitis, cholera, plague, tetanus, etc.” (Am I the only one who sees some Miró here?)
(O Malho, Rio de Janeiro, 1919)
