ANTHRACOID DISEASES. 



There remain for consideration two forms of anthrax 

 characterized by pathological lesions of special parts. These 

 are glossanthrax and anthracoid angina. 



Neither has as yet been demonstrated to be due to 

 the presence of bacillus anthracis in the blood. Neither 

 form is common, and both are generally found associated 

 together. By some authors they are termed anthracoid dis- 

 eases (dv6pa^ and s/dog, like). 



Glossanthrax. — The local symptoms which are rapidly 

 developed in glossanthrax probably slightly precede the 

 general disturbance of the system. Glossanthrax is a rare 

 disease, and is generally associated with anthracoid angina. 

 There is an eruption of vesicles, or phlyctenae, on the sides, 

 dorsum, and sometimes on the froenum of the tongue, and on 

 the buccal membrane of the mouth and lips. 



The vesicles vary in size from a nut to a hen's egg, and 

 contain at first a clear yellowish serum, Avhich gradually 

 becomes of a brownish-black colour. They rapidly increase 

 in size, and break, and the acrid contents are discharged, 

 being mingled with the abundant flow of saliva. 



The tongue itself is swollen and hard, hanging from the 

 mouth, and is of dark bluish or black hue. 



It is often lacerated by the teeth, and deglutition becomes 

 difficult, and the animal is soon unable to swallow fluids. 



When the vesicles have burst, they leave an unhealthy 

 ulcerated surface, which often has a gangrenous appearance, 

 and becomes coated over with a yellowish exudation. This 

 is removed, and exposes the ulcerating sore. 



The vesicles usually form a few hours before death, and 

 the constitution, previously not aff'ected, becomes seriously so, 

 and the animal usually dies in twelve to twenty-four hours. 

 The condition of the tongue is often associated with inflam-
