✦ Synopsis

This paper gives detailed description of the calorimeter designed to determine the latent heat of vaporization of ammonia. This important refrigeration constant was determined through the temperature interval -42 Β° to +52 Β° C. At o Β° the latent heat is 3Ol.8 calories per gramme. The results of 34 separate determinations agree with the mean within one part in one thousand.
