Abstract
IN Nature of August 10, p. 196, King, Temple and Thompson have described under the above title an infra-red spectrometer in which the spectrum is displayed on a cathode ray oscilloscope. This spectrometer is virtually identical with the one which we described in Nature earlier this year (April 27, p. 547), except that the trace is smoothed after rectification. The impression conveyed by their communication is that theirs was a parallel piece of work, which was concluded shortly after ours and was done quite independently. No mention is made of the fact that our spectrometer was demonstrated to Dr. Thompson on February 28, when full details were given of our procedure, and that it was only after this information had been given that work was started at Oxford on this project. Furthermore, the modification mentioned, and claimed as an advance, was introduced by us some three months ago, and Dr. Thompson was informed of this several weeks before the date of his communication to Nature.
