GLANDERS AND FAECY. 247 



swellin<Ts, wliich are due to inflammation of the ducts and valves, 

 point and burst, giving exit to a thin, purulent, yellowish 

 material, wliicli generally soon dries, and forms a yellow crust 

 on the surface of the ulcer. These buds are generally found 

 in groups, and away from the articulations. 



In some instances farcy manifests itself by, first, the formation 

 of a single painful swelling, which runs on to suppuration, on 

 the flexor tendons of a limb, below the hock or knee, and from 

 which enlarged lymj)hatic vessels may after a time be traced. 

 Other swellings form on various parts of the affected limb, with 

 intervening enlarged lymphatic vessels, which ultimately burst 

 and present ragged-edged, confluent, unhealthy-looldng sores 

 that discharge copiously. 



In otlier instances, farcy is preceded by symptoms of rheuma- 

 tism in some part of the body. Sometimes the muscles of the 

 neck become acutely painful, and very often, but not always, 

 swollen. The pain and swelling may disappear as suddenly as 

 they came, and appear in some other part of the body, and this 

 may occur repeatedly before any diagnostic signs of farcy mani- 

 fest themselves ; or the seat of pain may be the muscles of the 

 chest, simulating pleurodynia or pleurisy, the animal groaning if 

 made to move sharply or suddenly, and with a catch in his 

 breathing diagnostic of thoracic pain. Again, one limb may 

 suddenly become swollen and painful, causing much lameness. 

 The tumefaction, heat, and lameness may recede, and attack the 

 other limb ; and such attacks may appear repeatedly and for 

 several months, tlie animal's general health during the remissions 

 being scarcely affected ; but at length the disease assumes a 

 more marked character, and unmistakeable symptoms of farcy 

 appear, or glanders results, unpreceded by any true signs of farcy. 

 In other instances, extreme lameness may appear in a limb 

 without any traceable cause, and continue for days, or even 

 weeks, without inducing any observable local change ; generally, 

 however, farcinous engorgement succeeds, and relieves excessive 

 pain, and as a rule extreme pain is not of long duration. But it 

 may be safely stated that equina is manifested in such a variety 

 of ways as sometimes to mislead the most experienced.
