The spores are located in the middle of the bacilli and are distinctly oval. They are difficult to stain, but may be demonstrated by any of the usual spore-staining procedures, such as MoUer's or Novy's methods. The bacilli themselves are easily stained by the usual anilin dyes, and gentian-violet or fuchsiii in aque- ous solution may be conveniently employed. They are not decolorized by Gram's method.

In section of kidney of animal dead of anthrax. eedures, the anthrax bacillus may occasionally be seen to possess a cap- sule. The capsule is never seen in preparations from the ordinary artificial media. Some observers have demonstrated them in cultures grown in fluid blood serum. In chains of anthrax bacilli, the capsule when present seems to envelop the entire chain and not the individual bacteria separately.
