Contagious Diseases and Their Suppression. 263 



thorough and frequent sprinkling with quicklime or 

 chloride of lime, spraying of the walls and stalls with 

 hot lime wash will also be beneficial. The bull may be 

 the source of contagion in a herd, so that the penis and 

 sheath of that animal should also be attended to; injec- 

 tions into the skin of a carbolic solution (two per cent.) 

 every two weeks have been recommended by some, others 

 preferring the administration of the drug in the food, 

 when given in this manner, the dose is from fifteen drops 

 to two drams, dissolved in half an ounce of glycerine 

 and fed in a bran mash, two or three times a week. Af- 

 fected animals should not be used again for breeding 

 until the vaginal discharge has ceased completely; a 

 change in the bull used is said to have a favorable effect 

 on the disease, he must, of course, be from a healthy 

 herd. 



Distemper of colts or strangles is a contagious disease

 disease being due to the streptococcus of Sehiitz. Horses 

 are seldom attacked with the disease more than once, 

 and owing to the consequences are more valuable, if 

 passed safely through the disease. The swelliing of the 

 submaxillary gland beneath the lower jaw, the high 

 fever, loss of appetite, the discharge from the nostrils at 

 first thin and sticky, later becoming thick, whitish-yel- 

 low and creamy, together with the age of the jjatient 

 render the recognition of this disease quite easy; later 

 on the hot tender swelling below the jaw points and the 

 contents of the abscess are soon discharged, as soon as 

 this happens the colt is at once relieved and begins to 

 recover, unless other diseases set in. Unfortunately
