ANTHRAX IN THE PIG. 309 



of the mouth vesicles form, which are rarely numerous; 

 sometimes there is but one about the size of a bean. There 

 is considerable inflammation around the seat of the vesicles, 

 which are themselves at first white, and some of a brownish 

 or blackish colour. They burst, and sloughing of the tissues 

 beneath occurs rapidly. There is a tendency to fetid diar- 

 rhoaa, discharge of blood with the excrement and urine, and 

 there is great prostration of the vital powers. The animals 

 die in from 24 to 48 hours from the commencement of the 

 disease. 



3. The Neck Anthrax Kropfbrandbeule of the Germans 

 Soie or pig ice of the French Setola of the Italians. 

 This form of anthrax is not so common as the foregoing 

 varieties. In this country it is very rare. Heusinger says 

 that it is common in Poland, Hungary, and southern Europe. 



The early symptoms are similar to those of other forms of 

 anthrax, and the features which characterise it are due to an 

 eruption over the parotid region or on the upper part of the 

 neck .Small boils form, on which the bristles are erect, 

 hence the names applied to the disease by continental 

 authors, such as soyon, maladie piquante, poil pique', setolone, 

 &c. The bristles are stiff and dry; the pig experiences 

 great pain if they are pulled, and around the base of each 

 hair there is a depression. The skin is discoloured and 

 usually of a purplish tint. The intense thirst, loss of appetite, 

 grinding of teeth, and dulness perceived at the early stage, 

 are but the premonitory signs of a severe fever; total inac- 

 tivity or a state of stupor supervenes. The mouth becomes 

 intensely hot and clammy; there is occasionally a free dis- 

 charge of saliva; deglutition is interfered with, and the 

 breathing is oppressed. Diarrhoea sets in, the affected parts 

 occasionally slough, erysipelas spreads from the neck down- 

 wards, and the animal usually dies on the third day of the
