the vegetable fibers of barley wliicli had penetrated the 

 gums of cattle and on the awns of grain mibedded in 

 their tongues. 



Lumpy Jaw can also be transmitted by coming in con- 

 tact with or eating food over which lumpy jawed cattle 

 have slobbered. A healthy animal eating such food with 

 very slight bruises or abrasions of the mouth will con- 

 tract the disease very readily. This disease is mislead- 

 ing as other organs are affected with the Ray Fungi or 

 the Bacillus of Actinomycosis, as the lungs and even the 

 digestive organs have been found to be affected with this 

 disease. 



Symptoms : External symptoms or signs are the only 

 means by which to ascertain the disease. Its exact loca- 

 tion is on the lower jaw bone near its angle. It may also 

 affect the upper jaw, but this is an exception and not a 

 rule. Internally it may affect the tongue, mouth, throat 

 or lungs, but rarely the intestines. This enlargement 

 continues to grow until it reaches the size of that of a 

 man's head, breaks and discharges pus. The animal be- 

 comes poor and emaciated, the hair takes on a dull, 

 roughened appearance and in many cases it is very diffi- 

 cult for it to eat, especially w^here the disease separates 

 the gums and bone from the teeth and causes them 

 to become very loose or to drop out. The animal in 

 the latter stages of this disease generally dies from 

 starvation. 



Treatment: Successful in its first stages. Soft, ni- 

 trogenous food should be fed, such as wheat bran mashes, 

 steamed rolled oats or barley, hay dampened with clean 

 water, so as to make it pliable. Hay containing woody 

 matter as stems, etc., should not be fed to an animal af- 

 fected with Lumpy Jaw as it tends to aggravate the dis- 

 ease. Internally in their drinking water give two drams 

 of Potassium Iodide morning and night. This treat- 

 ment, however, should be omitted when the animal's skin 

 becomes scaly or when an excessive watery discharge
