hypsometers

Updated: June 30, 2026

I have previously had several severe attacks of snow-blindness. We had two photographic cameras, an air thermometer, two aneroids with altitude scale to 15,000 feet, and two hypsometers. The hypsometer is only an instrument for determining the boiling-point, which gives one the height above the sea. The method is both simple and reliable.
