The first mention of pigment producing growth is of great antiquity. It aroused the suspicion of the ancients, worked on the religious zeal of the people of the Middle Ages, and today solicits the study and investigation of modern scientists. In the light of our present cultural means of study the chromogenic group of bacteria is especially interesting. The products can be easily watched and as easily segregated. Each organism can be classed together under color and can thus be definitely recognized. The B. prodigiosus is such an organism. It responds fully to laboratory methods. It has been thoroughly studied and is one of the first specimens to be put into the hands of beginning students. Among the yellow bacteria that have been carefully investigated may be mentioned Sarcina aurantiaca and S. lutea.
