(Murray's ` Handbook of Switzerland.') The recipe is an excellent one ; pedestrians and teachers of gymnastics all endorse it.
Rarefied Air, effects of.-On high plateaux or mountains new-comers must expect to suffer. The symptoms are described by many South American travellers ; the attack of them is there, among other names, called the puna. The disorder is sometimes fatal to stout plethoric people; oddly enough, cats are unable to endure it : at villages 13,000 feet above the sea, Dr. Tschudi says that they cannot live.

The symptoms of the puna are giddiness, dimness of sight and hearing, headache, fainting-fits, blood from mouth, eyes, nose, lips, and a feeling like sea-sickness. Nothing but time cures it.
