Greig Smith describes the streak on slant glycerin agar as "a thin, broad, translucent white, moist, glistening growth, with turbid condensed water. The color deepens to a prim- ; On agar containing 10 per cent saccharose and per cent peptone there is a thin, white fluid growth, which gravitates into the condensed water, in which there is a yellow sediment (RGS.). A very good medium is a solution of 4 per cent agar added to an equal amount of neu- tralized cane-juice containing per cent peptone. With a greater per cent of peptone there is better growth at first, but ultimately less (RGS.). The writer obtained a very copious growth on slant tubes of sugar-beet agar, as much growth as on cane-juice agar. This medium was made as follows: Juice of sugar-beets 300, *Fig. 29.—-Flagella of Bacterium vascularum stained by Lowit's method.
