[Gk. coal.] This was the name formerly given to the painful swelling or eruption now called carbuncle. It is now used for a disease often fatal to sheep and cattle, and occasionally attacking man. It is also destructive to horses and camels and many of the smaller animals. When acute, the animal falls and goes into convulsion's, and soon dies. The disease has been known by many names. In man it is called Malignant Pustule, Wool-sorters' Disease, etc. It is believed to be due to a minute germ, named bacillusanthracis, which enters the system and multiplies in the blood with great rapidity.
