 burn the wound well with it ; but if you have not got these, burn the 

 wound well with a red hot iron, which will also kill the poison. 



LUMPY JAW (ACTINOMYCOSIS). 



This disease is contagious and spreads among cattle. It is 

 caused by germs known as "actinomycosis." This disease gener- 

 ally affects the upper or lower jaws, but may affect the tongue 

 and other parts of the body. The way this disease is communi- 

 cated from one animal to another is from the affected animals 

 slavering on the grass or over feed and other animals take it up 

 when eating or drinking. These germs pass down into the bowels, 

 where they are taken up into the blood and carried around until 

 they locate in the jaw. They may also be taken into the system 

 from the slaver getting into the wound on another animal, and it is 

 thought that this disease may be carried to and affect man by 

 eating the flesh of an animal affected with this disease. 



Symptoms. — If it affects the jaw there will be a hard, bony 

 lump form opposite the roots of the teeth, either in the upper or 

 lower jaws. The disease gradually works in the jaw, the lump 

 grows, and in the course of time the disease gets so bad that the 

 teeth loosen and fall out, and on account of the disease being so 

 bad that the animal cannot eal, it falls off in condition and dies. 

 If it affects the tongue, it is generally the thick part at the back 

 that is affected. It thickens and hardens the tongue so much that 

 when this is affected, it sometimes receives the name of wooden 

 tongue; in this case the animal will fall off in condition, from not 

 being able to eat, and will soon die. 



Treatment. — If more than one animal in a herd becomes 

 affected with lumpy jaw, and after examining the teeth you find 

 nothing wrong with them and you cannot see the mark of any 

 injury outside around the jaws, and if they are not sore to handle, 

 then be suspicious of this disease and treat in the following man- 

 ner : Separate the affected animals from the sound ones ; treat 

 the affected ones by throwing and securing them, then skin a 

 piece of the skin off the upper part of the lump, and take a 

 quarter-inch auger or a trephine, which is an instrument used 

 for boring into the bone, but an auger will do just as well ; bore 

 two small holes well into the bone, which is easily done when 

 the bone is diseased ; pour tincture of iodine into the holes 

 and let it soak well around the diseased bone ; let the animal
