Some constitutions are so tender that every cold blast is sufficient to produce inflammation and others are so susceptible of disease that they fall sick under the slightest faint of every epidemic disorder. Such sickly constitutions must watch against the east wind and not expose themselves to the air of the marshy fen [swamp]. But just such cold-catching, feverish invalids are we all in soul, whatever be the vigor and health of the body. Let us then be afraid of the very breath of the world, lest it chill the heart or inflame the carnal mind: let us dread exposure to its infectious influence lest it call forth into active energy our latent disease.
