I n a previous paper (Buschke, Friederiwald, Moses, '43) the cytological changes in the rat's corneal epithelium following exposure to ultraviolet irradiation were reported. In that preliminary study, an unscreeiied cold quartz mercury vapor a r c was used as the source. Several different effects were noted with varying intensities of exposure. It seemed of interest, therefore, to test the effect of exposure to monochromatic ultraviolet radiation of various wave lengths in order to determine the distribution throughout the spectrum of sensitivity for the various effects noted.

A medium pressure quartz mercury asc capillary drawing approximately 1000 watts was used as the source. The arc was cooled hy being iinizlersed in a water jacket with rapid water flow. The radiation emerged from tlie water jacket through a quartz window, and was dispersed into a spectrum by a quartz monochromator. Radiation of the selecid wave length enierged from the iiionochromator through a rectaiigular slit yielding a slighting diverging beam.
