 ing influences and mal-hygienic conditions. 



ymptoms. — The first symptoms are those of fever. 

 Eigors set in, and elevation of temperature to 106° or even 

 to 108° may occur, but this height is not often reached. 

 There are local swellings, generally confined to the extremi- 

 ties. They manifest themselves by engorgement of a whole 

 limb, and resemble the swellings of acute lymphangitis. 

 The engorgement appears as a generally difi*used swelling, 

 involving the cutaneous and underlying tissue, and the limb 

 is hot and painful, and there is marked lameness. As the 

 general oedema subsides, specific nodules, * farcy buds,' and 

 an enlarged condition of the veins and lymphatics become 

 more manifest. Sometimes the oedema is not so generally 

 diff'used, but occurs in localised circumscribed forms, on 

 which the specific buds arise. The lymphatics reaching from 

 these buds to the lymphatic glands, or reaching from one bud 

 to another, become enlarged and corded. The nodules gene- 

 rally appear in the oedematous tissue somewhat suddenly, 

 and are situated in the skin or the subcutaneous tissue, and 

 may extend even to the muscles. They vary in size from 

 a pea to a marble, and are not sharply differentiated from 

 the surrounding tissue. In a few days the buds disintegrate 

 and the sores are formed. These farcy ulcers, several of 

 which may coalesce, are deep, with ragged edges, and tend 

 to extend and discharge an abundant creamy fluid tinged 

 with blood. 



As in the ulcers of glanders above described, the floor and 

 sides of these rodent sores of farcy are covered with rounded 

 elevations resembling vascular granulation-tissue. 



Distinct nodules, which soften and discharge a yellowish 

 purulent fluid, develop in the painful, swollen, and corded 

 lymphatic vessels. The ulcers thus formed have likewise a
