Crab-Shell Barometer.

A curious and simple barometer is used by the people who inhabit the southern-most province of Chile. It consists of the cast-off shell of a crab. The dead shell is Bald to be extremely sensitive to atmospheric changes, remaining quite white in dry weather, but indicating the approach of moisture by the appearance of small red spots, which grow both in number and in size as the moisture in tho air increases, until finally, with the actual occurrence of rain, the shell becomes entirely red, and remains so throughout the rainy season.
