XIII] MICROBES OF MALIGNANT ANTHRAX 295 



appear as thin rods in rows, thus forming a leptothrix-Hke 

 growth. In some of the long filaments the individual bacilH 

 are not well shown. The filaments are either straight or 

 more or less curved. The length of the single bacilli varies 

 from 4 ;«, or less to 8 /x, or more ; the thickness is about i /x.

Many of them contain spores. In the ear of the rabbit 

 they invade the connective tissue as well as the cartilage 

 over the whole extent of the ulceration and its neighbour- 

 hood. Lingard found the same bacilli, having the same 

 arrangement, in a case of noma in the human subject.
