 soreness, and some times discharge of pus from the urethra

 the stallion off for a week or ten days. The stud-groom 

 should not allow service to any mare with a discharge 

 from the genitals. 



Calf cholera or dysentery is a contagious fatal disease

 death in twenty-four hours; the usual duration of the 

 disease being one to three days; the rate of mortality is 

 very high 80 to 100 per cent. Scours due to errors 

 in diet, is of a milder character and does not occur 

 so soon after birth and is non-contagious. The 

 liberal use of antiseptics is the cardinal feature of the 

 preventive treatment, the udder should be purified, the 

 vagina be washed with an antiseptic fluid, and pregnant 

 cows removed before calving from an infected shed to a 

 clean or disinfected one. For the calves, creolin, one 

 to two drams in two ounces of castor oil is very useful 

 in the earlier stages, a powder of opium, catechu, and

 to prevent this fatal disease. Some results of the inves-
