ABSORPTION SPECTRA OF A NUMBER OF SALTS 



region near X6500, and reach a maximum transmission over the region near 

 X7000 to X8000. The curves then descend, showing a series of small absorp- 

 tion regions near X8400, AS900, and A9800. The last of these absorption 

 bands shows a fairly sharp edge toward the shorter wave-lengths. Beyond 

 A10,500 the absorption increases rapidly until the region is reached where 

 water is practically opaque.
