    Cultures in bouillon are very fetid, and exhibit lance-shaped cocci (bacilli) ; also bacilli with clear interspace and bipolar staining and curved chains of five or six; there is also a short, thick bacillus in gas vacuole; this organism is present in common putrefaction. The cultures from gelatin are less gross than those from bouillon, exhibit more clearly the intermediate clear space. The odor of gelatin cultures is as fetid as the bouillon; the above applies to cultures of the cervical lymph glands of dog 17 and the heart blood of rabbit R in gelatin, below referred to (rabbit R trephined from medulla of dog 17). This bacillus with rounded ends, bipolar stain- ing and clear interspace, varies in size in the same media, differs in size in different organs and structures; it is the well-known bacillus of rab- bit septicaemia, and further reference to its mor- phology and mode of growth is out of place on this occasion; lenses of good definition are in- dispensable because the organism is often very short, and the clear interspace very narrow; easily mistaken for juxtaposed cocci. The ordinary carbol-fuchsin stain, if allowed to remain but a few seconds on the cover smear, gives satisfactory results.
