contact with a diseased one or when fed and 

 watered in infected vessels. The seat of trouble 

 is largely restricted to the respiratory organs, oc- 

 casionally causing difficulty in breathing, owing to 

 swelling in region of throat or to accumulations in 

 air passages. 



The symptoms start out with more or less slug- 

 gishness. The animal eats little, and does not 

 care to take much exercise. A little watery 

 discharge frequently appears from the eyes, and 

 about the same time a watery discharge from 

 the nostrils, which soon becomes thicker and 

 more yellow in color. Usually the glands between 

 the lower jawbones become enlarged and undergo 

 suppuration with a rupture of them and free dis- 

 charge of pus. The temperature of the animal may 

 be slightly or very greatly increased from 103° to 

 105°. The pulsations may also be considerably 

 quickened. When complications do not occur this 

 disease usually runs its course in two weeks, leav- 

 ing the animal little the worse for having passed 

 through the affliction. 



The milder forms of this disease will need little 

 or no treatment other than careful feeding and nurs- 

 ing. A laxative diet, with something green, if pos- 

 sible, should be given. The colt should be placed 

 in clean, airy, and comfortable quarters, but not 

 in a draft. To hasten the suppuration of the 

 glands a poultice of hot bran or flaxseed may be 

 applied to that region, and as soon as softening can 

 be detected within, puncture the gland containing 

 abscess with a clean knife blade and allow the 

 escape of the collection of pus. During the course 

 of the disease the animal should not be worked and 

 care should be taken that it be not exposed to con- 

 ditions likely to produce a cold.
