EPIZOOTIC APHTHA. 321 



allowing the calf until several weeks old to suck its own 

 mother, not only morning and night, but at least three 

 times in the day, and divide the periods as evenly as pos- 

 sible. Thus by allowing calves to suck the milk for them- 

 selves paralyzation and gorging the stomach with cold

 milk and fitting it for assimilation.

Dysentery. — (See Consumption and Chronic Diar- 

 rhoea.)

 through an opening below the chest, and sometimes even 

 in the abdomen. The animal vfill have to be killed. 



Epizootic Aphtha, — Murrain. — In some parts of the 

 world, this disease is called murrain. This is one of the 

 epizootic diseases of cattle, attacking the feet and mouth, 

 and sometimes extending to the teats of the udder. 



Causes. — Contagion is believed to be the cause, but I 

 never can be reconciled to believe in this repeated bug- 

 bear, contagion as being the only cause of certain dis- 

 eases. We all know, however, that when a disease is 

 once established it can then effect others, but still we 

 must consider that all diseases of whatever kind, must
