As a brief introduction to the subject matter of this paper, a review of the various devices used in energy measurements will not be amiss. The devices are not numerous, and they are familiar to everyone at all conversant with the methods of physics. They are the thermometer, the differential thermometer, the thermopile, the bolometer, the radiomicrometer, and the radiometer. Several other devices have at different times been suggested and used, but the above represent the most important ones.
