COMMON DISEASES. 



sometimes by chronic cough. Certain glands between the branches 

 of the lower jaw are affected in a peculiar way. 



Acute cases. — When the cases are acute, small tubercles de- 

 velop rapidly on this mucous membrane and soon change to small 

 ulcers which increase in size and even coalesce. Thus is developed 

 the peculiar ulcer of glanders with its dirty gray base and over- 

 hanging edges. The dis- 

 charge from these ulcers is 

 quite distinctly viscid. Very 

 large ulcers and even rag- 

 ged gutterlike excavations 

 may develop, particularly 

 on the nasal septum. The 

 ulcers may heal, leaving 

 light colored more or less 

 star shaped scars. 



The fever may be se- 

 vere in acute glanders, the 

 temperature rising rapidly 

 to 105 or even 107, and 

 then be quite variable for 

 a few days. There may be 

 also persistent chills. 



There is apt to be a de- 

 velopment of \^-shaped 

 areas of lung inflammation 

 in the more acute cases. 

 Occasionally there is a par- 

 tial or apparent recovery from the acute symptoms and then 

 the development of a chronic case. 



The lymphatics become involved. Certain enlarged glands 

 may be found. 



These glands are located well up on the inside of the jaws 

 and more or less adherent. Glanderous disease of these glands 

 may usually be distinguished from other involvements, as for in- 

 stance, in strangles (distemper) and laryngitis. In glanders they 

 have a peculiar nodular feeling, which is not characteristic of 

 other troubles. 



Chronic cases. — If the disease be chronic then these same 

 symptoms in general develop less rapidly. The chronic pulmonary
