✦ Synopsis

A DESCRIPTION is given of a portable vacuunl thermopile, of glass, in which a calcium evacuator is permanently attached to the container. The paper gives general directions for operating the device, as well as data on the thermopile, which is of bismuth-silver.

Observations extending over a period of about seven years are given on the behavior of vacuum thermopiles in Which the vacuum is maintained by means of calcium, which has the property of combining with gases when it is heated.
