The boiling-point of sulphur on the constant-pressure air thermometer

Abstract

The following experiments were undertaken at the suggestion of Professor Callendar, with a view to the redetermination of the boiling-point of sulphur (S. B. P.) on the scale of the constant-pressure air thermometer. The experiments unfortunately have not led to a result that can be regarded as final, owing to the uncertainty in the expansion of the glass, but it has been thought desirable to publish the results. The air thermometer was made of Jena glass, 16 III, and is in construction substantially the same as that described by Callendar. Fig. 1 will make clear the form of the apparatus, and is drawn roughly to scale.
