No. 6. — The cow in the picture is an advanced case of tuberculosis. She is 

 very weak and thin, but a heavy milker and in her weak condition 

 continues to give an abundant quantity of milk. 

 Cows of this kind are unfortunately too numerous in dairy herds. 

 The temptation to keep such cows and to use their milk is greater 

 than some persons can resist. Such cows are a great danger to 

 other animals that may come in contact with them and the use of 

 their milk in a raw state is very apt to cause tuberculosis alike in 

 young persons and lower animals.
