animals in menageries, by means of infected horse 

 flesh, and also by means of inoculation to field mice, 

 guinea pigs, dogs, cats, goats, rabbits, and sheep. 

 Pigs are not readily susceptible and cattle appear 

 to be immune. Like all diseases of a contagious or 

 infectious character, glanders is due to a specific 

 organism, known as the bacillus malleus. 



The external manifestations of glanders differ 

 and consequently the disease is spoken of as glan- 

 ders or farcy, depending upon the symptoms pre- 

 sented. The disease is known as glanders when the 

 horse suffering from it has a discharge from the 

 nose, ulcers on the septum nasi (the partition divid- 

 ing the nasal cavities) and enlarged submaxillary 

 glands, and is known as farcy when the affected 

 animal has farcy " buds " or ulcers on the skin, and 

 corded lymphatic vessels running from one " bud " 

 to another. In farcy, the corded lymphatics, " buds " 

 and ulcers on the skin are very apt to be on the 

 inside of one hind leg or the other, but may appear 

 on the inside of a fore leg, or on the neck or body. 



Farcy was, in olden times, thought to be a different 

 disease from glanders, and was believed by many 

 to be curable, while glanders has always been gen- 

 erally believed to be incurable, but it is now known 

 that farcy is simply one manifestation of glanders. 

 It has been found that a horse with glanders may 

 give another farcy, and vice versa. Guinea pigs 

 inoculated with the discharge from a glandered 

 horse's nose will develop glanders, and pure cul- 

 tures of the glanders bacillus can be obtained from 

 them, and in a similar way if guinea pigs are in- 

 oculated with the discharge from a sore on a horse 

 with farcy glanders may be produced in these little 

 experimental animals, and upon post mortem ex- 

 5^mination pure cultures of the glanders bacillus can
