REPORTS OF CASES.

About October io the patient received an accidental wound 
of the coronet of the right hind foot on the outer side, apparently 
due to a tread from the dam. Careful disinfection brought about 
an early subsidence of lameness, and the wound apparently 
healed in five or six days. 
On October 12 a careful digital exploration revealed a very 
small communication with a deeper seated abscess, which had 
its location in the popliteal space. This was freely opened and 
.5 liter of pus evacuated. 
The cavity reached from the gastrocnemius upwards to a 
level with the ischiatic tuberosity ; this was packed with anti¬ 
septic gauze and carefully dressed daily. 
No marked improvement occurred. These abscess cavities 
healed slowly, but the emaciation and debility grew apace. The 
abscess walls were indefinite, soft, and bore shreds and masses 
of necrotic tissue. 
On October 19 an abscess had appeared in the inguinal 
lymphatics, which was freely opened and carefully dressed. 
October . 1.—Patient much worse, showing rapid, shallow 
respiration, with a profuse nasal discharge of a dirty reddish 
color, very foetid. The right side of the chest was non-resonant. 
Auscultation revealed the presence of liquid (pus) in the bronchi. 
Abscess of lungs was diagnosed and early death anticipated. 
The patient grew rapidly worse and died on October 24. 
Autopsy.—In the coronet at the right side of the left hind 
foot there was still pus visible in the tissues at the seat of the 
accidental wound, which occurred during presence at the clinic 
about October 10. The suppurating tracts about the tarsus 
were almost completely healed and showed nothing notable. 
The large abscess cavity of the popliteal space extended 
from gastrocnemius to ischial tuberosity. The walls were ill- 
defined, soft, with much pus and necrotic shreds, and within the 
walls numerous suppurating areas. 
The opened inguinal abscess offered nothing of interest. At 
the anterior end of the sheath of the penis on the left side the 
lymph glands were enlarged, and on section were found suppu¬ 
rating. 
The sublumbar lymph gland of the left side was the seat of 
an abscess 6x10 cm. in size. 
The mesenteric lymph glands of the colon varied from .5 to 
3 cm. in diameter, and were filled with pus. 
The posterior mediastinal lymph glands had undergone sup¬ 
purative destruction, forming an abscess 7 cm. in diameter,
