Letters 95.17

Why need I mention dizziness? Or speak of pain in the eye and in the ear, itching and aching in the fevered brain, and internal ulcers throughout the digestive system? Besides these, there are countless kinds of fever, some acute in their malignity, others creeping upon us with subtle damage, and still others which approach us with chills and severe ague.
