  1. Published by permission of the Director, Bureau of Standards.
  2. Numbers in parentheses, followed occasionally by page or figure references, refer to the Bibliography at the end of the paper.
  3. Further discussion of these relations is given in references 16, 17, 19, 23, 33, and 36 of the Bibliography.
  4. Dr. H. P. Gage of the Corning Glass Works kindly informs the writer that a water cell in combination with Corning glass G 392 H will absorb all the infrared. Reference to Dr. Gage's paper (Ref. 14 of the Bibliography) will furnish considerable information of value in the use of colored glasses as filters.
  5. The data given in Fig. 3a represent perhaps the most efficient experimental conditions for isolating the region below 300 mµ. The author also gives the following values of "percentage of light transmitted" through a mixture of chlorine and bromine which "comes near to concentrations of Cl and Br at normal conditions of temperature (18°) and pressure (740 mm)," (Ref. 33, Eng. Trans., p. 398). The cell thickness was 10 mm and the molar concentrations 0.044 and 0.0046 for the chlorine and bromine, respectively.
  6. All the filters for isolating the green and yellow mercury lines transmit freely in the red, and it may often be necessary to combine a blue-green glass (absorbing strongly in the red) with the filters noted in the references before satisfactory work can be done with these lines. This is especially true with the quartz-mercury arc which shows an appreciable red continuous spectrum in addition to the weak red lines.
  7. The author is indebted to Messrs. H. J. McNicholas and F. K. Harris for these measurements.
