the bead is poked out, a little frothy saliva exudes 

 from its mouth, sooner or later there will appear 

 a swelling between the jaws, or sometimes at the 

 back of the jaw; when this takes place the animal 

 has great difficulty in swallowing water and food, 

 especially t he former. In some cases there is very 

 little fever and the appetite remains good. In 

 others there may he considerable fever, pulse sixty 

 to seventy. In the course of a few days the inflam- 

 mation relieves itself in the formation of matter, 

 which will soon come to the surface and break of 

 its own accord if not opened. After this takes 

 place the animal is much relieved. Cases may be 

 met with where a small abscess may form and the 

 animal may show no other symptoms; this soon 

 breaks, discharges and heals. In others, although 

 not very sick, the condition of ill health may con- 

 tinue for several weeks, and finally an abscess ap- 

 pears, matures, and the animal soon recovers.

 the abscess forms on the outside it is not danger- 

 ous to life, but those on the internal organs usually 

 cause death. The sequel of distemper most fre- 

 quently occurring is a thickening of the lining of 

 the throat, which interferes with the animal's 

 breathing, causing what is called roaring or whis- 

 tling. The more serious sequel is blood poisoning
