Biological Characters. It does not grow at room-tem- perature, but only in the incubator, and its develop- ment is usually scanty on the surface of agar, but some- times a few colonies grow quite vigorously. It does not grow at all or scarcely any in bouillon, and very scantily in bouillon plus one-third blood-serum. It grows comparatively well on Loffler's blood-serum medium as used for diphtheria cultures. When grown on nutrient agar or glycerin-agar, at the end of forty-eight hours in the incubator, there develops a tolerably good growth, appearing as a flat layer of colonies, about one-eighth of an inch in diam-.
