Gapes 353 



The best treatment is to destroy the chick as soon as 

 the disease is noticed and burn the body, thus preventing 

 the spread of the disorder. If possible, shift all healthy 

 chicks to uninfested ground, but if this is not practi- 

 cable, the quarters should be thoroughly cleaned and dis- 

 infected. If care is taken to detect and remove the first 

 ease of the gapes as soon as it is discovered, there is 

 little danger of its spread. 



In some eases, the worms can be removed from the 

 trachea by using a feather, — stripping the vane till 

 only a small tip remains at the end, and inserting this, 

 wet with kerosene or turpentine, into the chick's 

 trachea when he breathes. If carefully given a few 

 turns, it will loosen the worms, and then they can be 

 removed. After a little -experience, a number of worms 

 can be removed by this means. They should be de- 

 stroyed, and the chick, after this treatment, should be 

 isolated until all danger is past. 



MEASLES IN MEAT 



"Measles" in meat is due to the presence of small, 

 yellowish spots scattered through the tissue (page 342) . 

 These yellow spots are the encysted stage of some kind 

 of tape-worm, and, if taken into the human system with- 

 out being killed by cooking, they will probably develop 

 into adult tape-worms. The measles, or cysts, are found 

 in the meat of the pig, ox, duck, chicken, dog, cat, and 

 rarely the sheep. They are most numerous in the 

 deeper muscle of the shoulder, back and neck, but they 

 may be scattered all over the body. Measly meat should
