582 VETERINAEY HYGIENE 



5 years old and upwards, he found to be 38 per cent. ; 

 from 3 years to 5 years 30-86 per cent. ; from 1 year to 

 3 years nil. In the Cheshire experiments the loss was 

 less; 5 years and upwards 12-47 per cent, on capital; 

 3 years to 5 years 13-33 per cent. ; 1 year to 3 years nil. 



The interest in these experiments consists in knowing 

 from actual observation what the cost of freeing a herd 

 roughly amounts to. It would be a comparatively simple 

 matter in the case of fattening oxen, but for dairy stock the 

 loss of even five pounds a head, with probably the tem- 

 porary paralysis of the man's trade, are conditions that 

 are difficult to accept with a light heart.

(6) Shall not be sold or used for human food ; and 



(c) Shall not be sold or used for food of swine, or other animals, 

 unless and until it has been boiled. 



An Order published in 1899 makes an important addition to the above 

 Article XV., for the purpose of the provisions of paragraphs a and b. 



Disease in the Order of 1889 includes, in the case of a cow, such 

 disease of the udder as shall be certified by a Veterinary Surgeon to be 

 tubercular. 



The enactment then, is this, that tuberculosis of the udder is 

 scheduled, but there is nothing to prevent the sale or use of milk from 

 a reacting animal unless the udder is affected. 



ANTHEAX. 



Anthrax is a widely spread disease and found practically 

 all over the world. The extent to which it exists in a 

 country appears to be intimately related to soil tempera- 

 ture, for it is impossible for the organism to develop when
