Abstract

MR. J. A. C. TEEGAN, writing in NATURE of February 25, mentions that the application of the electrometer triode to X-ray ionisation spectrometers is under consideration. I have successfully used this valve for this purpose during the past three years and saw it in use in Germany even earlier.
