The color, at first white, changed to yellowish-white and then to a decided pale yellow. The well-developed coloniescling firmly to the surface of the medium and were not easily detachedor broken up. The growths in all of the tubes were absolutely pure,and consisted of branching threads like those found in the sections. Lofflers blood serum seems to be the most suitable medium forcultures. The growth on this medium is more^ rapid and abundantthan on any of the other media tried. On plain
