Abstract
IT has long been realised that the only really certain method of comparing masses by observations on mass spectra is by resolving and measuring naturally occurring doublets which represent small residual differences between the atoms and molecules concerned. The recent discovery of deuterium has enabled this method to be applied generally to the lighter elements, and for some time past I have been constructing parts of a new mass-spectrograph designed for this work. One of these, a new collimator with variable slits, has been tested on the instrument now in use, with results of great interest.
