Sorocho

New-comers upon those elevated parts of the Andes suffer from "puna," or "sorocho," an acclimation disease, characterized by piercing chilliness, headache, and nausea.

The facts probably are that the ordinary symptoms of sorocho are aggravated by the putrid emanations from the tombs, and the virulent diseases result from the latter cause.

A traveler who has explored the mountains of Bolivia and reru, in search of gold and silver mines, tells me that Indian postilions, using coca freely when driving pack-mules over the roughest roads along the Sierras, even when the sorocho prevails, outstrip well-mounted horsemen.
