Etaulin's fluid, characteristic growth. < John's solution, germination only. Synthetic fluid(Dox's), carbon supplied as: Cane sugar, 3-30 per cent, characteristic growth and colors, hut not normal at 00 percent, with acid reaction. Lactose 3 per cent, characteristic structure but weak development. Lactic acid per cent, growth, hut not normal colonies. Levulose :5 per cent, slow development, small colo- nies. Galactose 3 percent, characteristic. Glycerin :'. percent, slighl growth, grew freely when cane sugar was added. Potato starch, characteristic.
