Interspecific transformation of Neisseria by culture slime containing deoxyribonucleate

Land has recently studied the perception of colors resulting from appropriate mixtures of two colors or of one color and light from an incandescent lamp. In an "image situation," colors of all hues may result from such mixtures. The findings presented demonstrate that the mixing which Land accomplished by superimposing two projected images on a screen can be achieved when the two color separation images are presented simultaneously but separately to the two eyes.
