Oxygen Compartments for Travelers.

On the nearly completed railway from Arica, Chile, to La’Paz, Bolivia, which goes to an altitude of 14,105 feet above sea level, the effect of the quick ascent and great altitude on people having weak or abnormal hearts, is to be counteracted by having * oxygen compartments in the passenger cars. Passengers subject to mountain sickness or any affection of the heart may, by occupying these compartments, breathe air having thp same percentage of oxygen as at sea level. —Scientific American.
