the external maxillary vein. B}' careful dissection the skin, subcu- 

 taneous fascia, parotid gland, and subjacent aponeurosis were retiected. 

 On passing the finger behind the left guttural pouch a large, rounded, 

 uniform, resistent swelling, without the least fluctuation, was detected. 

 For the moment it was doubtful whether this represented a new growth 

 or a cold abscess in the retro-pharyngeal glands. The end of a grooved 

 director was introduced, guided by the left index finger, and was pushed 

 in the direction of the centre of the swelling. It appeared to enter, 

 and some whitish laudable pus escaped. The tract was enlarged, and 

 about a pint of similar pus evacuated. The abscess cavity was washed 

 out, a rubber drainage-tube inserted and fixed to the skin, and the 

 animal allowed to rise. On entering the stable it at once began to eat 

 some oats, which it swallowed without difficulty. The swelling about 

 the throat had almost entirely disappeared, and the head and neck 

 were moved freel}-. During the evening and following da3S the abscess 

 cavity was washed out with antiseptic solutions. Suppuration was 

 trifling. 



On the 14th the drainage-tube was removed. On the 20th the 

 guttural region had resumed its ordinary appearance, except for the 

 cicatrix of the operation wound. Respiration was unaffected, and 

 appeared normal at all paces.
