ation of large swellings or tumours — two, three, four, five, or six, 

 and even more — on diflbrent parts of the body. These tumours 

 either adjoined each other, or communicated by a kind of cord. 

 They ordinarily appeared on the throat, the neck, the breast, or 

 the inferior parts of the chest and belly, the scrotum or sheath, 

 or within the thighs. They also appeared about the eyes, the 

 jaws, on the lips, the shoulders, the haunches, and on the 

 sides of the chest and abdomen. They were more or less indo- 

 lent, and so little endowed with sensibility that in handling them 

 the animals exhibited no pain. The impression of the fingers 

 remained on them for some time, and when they were opened a 

 serous fluid, more or less abundant, and of a reddish yellow or 

 bloody colour, escaped. The subcutaneous cellular tissue was 

 spongy and distended with a yellow glairy matter resembling old 

 and rancid lard. It was also sometimes of a pale red tint, similar 

 to the feeble granulations of certain ulcers; and showed hydatids or 

 small vesicles. The cellular tissue, and with it the adipose layers, 

 were the textures chiefly affected, and after them the glands. This 

 accounted for fat animals being more commonly attacked than 

 lean ones, and for the tumours appearing so often in certain situ- 

 ations ; it was not because the humour gravitated to the depend- 

 ent parts, as the vulgar and the farriers supposed, but because the 

 cellular tissue contained more fat, was more elastic, and less 

 compact and resisting than other textures; this also explained 

 the sudden formation of these tumours, as well as their metastasis 

 from one part to another. After the excision of these swell- 

 ings, the flesh, of a bright red colour at the time of extirpation, 

 became in some days yellow, then dead livid, blue, or black, form- 

 ing a large eschar without caustic. They were regarded as buboes 

 if they attacked the glands, and as carbuncles when they appear- 

 ed elsewhere. The blood drawn from the animals attacked, or 

 even from those bled as a precautionary measure, bubbled more or 

 less, and was thick and viscid ; its colour varied much. The dis- 

 tress the animals manifested was very great; notwithstanding 

 tluMr violent throes, they yet seemed, by their agony, their moans, 

 and their docility, to ask assistance. The majority of them in- 

 dicated the seat of pain by turning their heads towards the af- 

 fected side. Some of the attacked died all at once, or in less
