Title

Radiometer holder [facsimile]

Description

The catalogue entry begins with a short description of how the radiometer works, and emphasizes that instructions issued with the Pastilles (a part of the apparatus) to interact with the instrument, must be followed meticulously if the results are to be of any value.
The four major areas of difficulty are reviewed, and the radiometer holder is introduced as a solution to the problem. Precise instructions on how to use it follow. The account ends with the instrument’s current price.
