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. Numerous trials have been
made with these unhappy feline barometers, and the creatures have been
found to die in frightful convulsions. 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. It begins to be felt severely at from 12,000 to 13,000
feet above the sea. M. Hermann Schlagintweit, who has had a great deal of
mountain experience in the Alps and in the Himalayas, up to the height of
20,000 feet or more, tells me that he found the headache, etc., come on
when there was a breeze, far more than at any other time. His whole party
would awake at the same moment, and begin to complain of the symptoms,
immediately on the commencement of a breeze. The symptoms of overwork are
not wholly unlike those of the puna, and many young travellers who have
felt the first, have ascribed them to the second.

Scurvy has attacked travellers even in Australia; and I have myself felt
symptoms of it in Africa, when living wholly on meat. Any vegetable diet
cures it: lime-juice, treacle, raw potatoes, and acid fruits are
especially efficacious. Dr. Kane insists on the value of entirely raw
meat as a certain anti-scorbutic: this is generally used by the
Esquimaux.

Haemorrhage from a Wound.--When the blood does not pour or trickle in a
steady stream from a deep wound, but jets forth in pulses, and is of a
bright red colour, all the bandages in the world will not stop it. It is
an artery that is wounded; and, unless there be some one accessible, who
knows how to take it up and tie it, I suppose that the method of our
fore-fathers is the only one that can be used as you would for a
snake-bite (see next paragraph); or else to pour boiling grease into the
wound. This is, of course, a barbarous treatment, and its success is
uncertain, as the cauterised artery may break out afresh; still, life is
in question, and it is the only hope of saving it. After the cautery, the
wounded limb should be kept perfectly still, well raised, and cool, until
the wound is nearly healed. A tourniquet, which will stop the blood for a
time, is made by tying a strong thong, string, or handkerchief firmly
above the part, putting
