THE VETERINARY SCIENCE 
lowing them up may take the germs into the lungs by eating 
or drinking out of the same pail or manger, or ofif the grass 
where the diseased cattle have been. In this manner the 
disease is communicated from one to the other. These germ? 
may also pass out of the system into the milk, and animals 
or people that drink the milk are liable to take the disease 
The danger of having a diseased cow around is therefore 
apparent. 
Fig. 71. — Appearance of Consumption. 
Symptoms. — At first the disease comes on very slowly 
after the germs are taken into the system. If afifecting the 
lungs there is a short, dull cough which may be noticed more 
in the morning, after exercise, or drinking. Later on the 
cough becomes more troublesome, the animal runs down in 
condition, the breath has a bad smell, there is a dribbling of 
saliva from the mouth, the animal becomes hide bound, the 
hair stands out and it is a pitiful looking sight. In a few 
months the patient pines away and dies. The time it takes 
the disease to run its course varies from three months to a 
year. 
It is noticed more in thoroughbred than in grade cattle. 
If affecting the bowels the animal runs down in condition, 
has diarrhoea sometimes, then costiveness, changing every 
few days. The other symptoms are the same, only when not 
affecting the lungs there is not such a cough.
