Though most commonly seen in the horse and ass, 

 glanders is not rarely met with in other animals, and is 

 occasionally encountered in man. When occurring 

 spontaneously in the horse its primary seat is usually 

 upon the mucous membrane of the nostrils. It appears 

 in the form of small gray nodules, about which the 

 membrane is congested and swollen. These nodules 

 ultimately coalesce to form ulcers. There is a profuse 

 slimy discharge from the nostrils during the course of 

 the disease. It may extend from its primary seat in 

 the nose to the mouth, larynx, trachea, and ultimately 

 to the lungs. Its secondary manifestations are observed 

 along the lymphatics that communicate with the primary 

 focus, in the lymphatic glands, and as metastatic foci in 

 the internal organs. Less frequently the disease is seen 

 to begin in the skin, particularly in the region of the 

 neck and breast. When in this locality the subcuta- 

 neous lymphatics become involved, and are converted 

 into indurated, knotty cords, easily discernible from 

 without. 



When occurring in man it is usually in individuals 

 who have been in attendance upon animals affected with
