Abstract
SOME years ago, results were published of measurements on the dielectric constant of carbon dioxide under pressures up to 1000 atm.1. Using Amagat's isotherm data, where available, the Clausius Mosotti function was calculated ; P is pro-portional to the polarizability of the molecule. It was stated that P showed a tendency to decrease, the decrease at 1000 atm. being about 1 per cent. It was considered not impossible at that time that this decrease was due to an uncertainty in the density d.
