breathing or broken wind are present. If the superficial lymphatics 

 are affected we have 



2. Chronic Farcy. — In this, nodes from the size of a bullet to 

 a walnut appear on the skin — hot, elastic and sensitive. These break 

 down into ulcers with irregular, overhanging edges and a grayish- 

 dirty base. The discharge has been described as having the appear- 

 ance of olive oil and the consistency of white of egg. Brownish- 

 yellow crusts form. Finally the discharge becomes purulent and 

 the ulcers heal by ordinary granulation. Farcy occurs on the lips, 

 the side of the neck, lower part of the shoulders, inside of the thighs 

 and outside of the legs. Radiating from the ulcers or chancres are 

 hot, tender, corded lymphatics which may ulcerate. With lung in- 

 volvement in glanders there is often sudden swelling of one hind 

 limb, which is hot, tender and edematous from stifle to pastern. 

 Serum exudes and then farcy buds appear. The testicles are often 

 acutely inflamed. Glanders is very chronic and may persist for 

 years. Loss of flesh, weakness and irregular fever are seen in ad- 

 vanced cases. 



3. An acute form occurs primarily or more' often terminates 

 the chronic cases. In this there is a high fever (io3°-io5 u F.), 

 rapid pulse and breathing, much nasal discharge, cough and farcy 

 buds. There are mucous and sibilant rales, but no dulness over 

 the lungs. Areas of bronchial pneumonia exist. Acute forms may 

 become latent and apparently recover with cough and heaves and are 

 a great source of infection, or eventuate in death within a few days 

 or a fortnight. 



An exact diagnosis is best determined by the use of mallein. 

 The mallein test is most valuable in animals with a normal 

 temperature, but in those with fever (over 102 F.) a large, 

 persistent swelling occurring at the site of injection renders the 

 existence of glanders probable. In many febrile cases the test is, 

 however, unreliable. 



To apply the test the temperature should have been taken for
