Specific Contagious Diseases. 135 



or beans, and are occasionally firmly adherent to the skin, 

 the tongue, or the jaw-bone. The lymphatics on the face 

 often rise as firm cords. An occasional cough is heard and 

 auscultation detects crepitation or wheezing in the chest. 

 The ulcers increase in number and depth, often invading the 

 gristle or even the bone, the glands also enlarge but remain 

 hard and nodular, the discharge becomes bloody, fetid, and 

 so abundant and tenacious as to threaten or accomplish suf- 

 focation, and the animal perishes in the greatest distress. 



Symptoms of Chronic danders. This is characterized 

 by the same unhealthy deposits and ulcers in the nose, 

 varying extremely in size and number, often, indeed, situ- 

 ated too high to be seen ; by the same viscid discharge, but 

 usually much less tenacious than in the acute form ; by the 

 same hard, comparatively insensible nodular glands on the 

 inner side of the jaw-bone ; and a cough, which, however, 

 is much more rare. Excepting at the very outset, the ani- 

 mal usually appears to be in the best of health, with the 

 apparently insignificant drawback of the nasal discharge, 

 and hence he is often kept and used till he contaminates a 

 number of horses or even men. The case is easily recog- 

 nized unless where the ulcers are invisible or the enlarged 

 glands removed. It is sometimes needful to inoculate a use- 

 less animal to decide as to the nature of the malady. It usu- 

 ally proves fatal to the inoculated animal in about ten days. 



Symptoms of Acute Farcy. The premonitory symptoms 

 resemble those of acute glanders, of which it is but another 

 manifestation. The local symptoms consist in thickening 

 of the lymphatic vessels, which feel like stout cords, painful 

 to pressure ; and the formation of rounded inflammatory 

 swellings (farcy-buds) along the course of these corded 

 lymphatics. There follow ulceration of these buds, raw 

 sores, discharging a glairy, unhealthy pus, and dropsical 

 engoi'gement of the limb or other part affected. It is usu- 

 ally seen to follow the line of the veins on the inner side of
