lymphatic glands enlarge, burst, and discharge a purulent mate- 

 rial. This fonn of glanders is rapidly fatal. 



Symptoms of the Chronic Form. — This fonn of glanders is 

 the most common, and is frequently seen in old, debilitated ani- 

 mals. The animal may be affected for some time without pre- 

 senting any well-marked symptoms. The general health is 

 scarcely affected. The submaxillary gland becomes intermit- 

 tently swollen and hard. The nostrils finally become paler, and 

 soon the starchy, glue-like discharge comes on. The discharge 

 usually issues from one nostril, although it may issue from both. 

 If the discharge is thrown into w^ater it sinks readily. In chronic 

 glanders, the ulcers in many instances are not present. There 

 will usually be a slight irrita- 

 tion of the eye on the same 

 side as the nostril that is dis- 

 charging. In order to bring 

 out the symptoms, ten drachms 

 of aloes may be administered, 

 when usually the symptoms 

 become more marked. If a 

 case is suspected, it should be 

 isolated. Some of the nasal 

 discharge may be inoculated 

 in the hind limb; if glanders 

 is present farcy will probably 

 appear. 



Acute Farcy. — The signs 

 are those of fever, the tem- 

 perature ranging from lOC^ to 

 108°. The first symptom to 

 attract attention is a swelling 

 of the limbs. There is an engorgement of the whole limb, 

 resembling the swelling of lymphangitis. The lymphatic 

 glands will be enlarged, showing cords and buds. These buds
