The reflex effect of white light was also obtained by focussing asmall butintense circular patch of white light from the arc upon theedge of a white porcelain plate. By fixating vision upon the edge of theplate a semi-circular patch like a half moon was formed on one side of Table 6. Luniinosily Contrast Darkness. Darkness. White X Normal Reflex Direct Light Sec.
