Make a cover-glass preparation from the same colonies and stain each with carbol fuchsin. Examine each carefully and make a drawing of a few of the isolated bacteria. Describe (30) the appearance of the bacteria in these preparations. Inoculate a tube of bouillon, one of agar and one of gela- tin from a w...ell isolated colony from one of the agar plates. 42. Suggestions for the examination of the plate and roll cultures.
