tion of the intimate lingual structure, but the scalding dose pro- 

 duces also a catarrhal inflammation of the mucosa. 



Cause. — The cause is invariably due to local injury. In cat- 

 tle it may take on the form of actinomycosis, tuberculosis, etc. 

 The horse is not often afifected with actinomycosis and tubercu- 

 losis is rare. 



In glossitis the tongue swells and protrudes between the in- 

 cisor teeth. The mouth hangs open and the tongue hangs out. 

 Deglutition is difficult ; the horse is unable to eat and he may be 

 unable to drink. Constitutional disturbances may occur. 



Treatment. — Ascertain the cause and remove any foreign 

 body. If a puncture is present, follow it to the bottom with a 

 probe-pointed bistury and enlarge the opening. Irrigate well 

 with an antiseptic ; if a large wound, bathe with an antiseptic so- 

 lution. Use water as warm as the horse can stand, carbolized 1 

 per cent or a 10 per cent solution of boracic acid or a saturated 

 solution of chlorate of potash. If the swelling does not yield 

 promptly, scarify the tongue on the side an inch long and 1-4 inch 

 deep. Bathe the tongue with water 102-3 degrees F. to promote 

 bleeding and then go on using the antiseptic solution. If the 

 mouth gets foul, sponge out twice daily with permanganate of 

 potash. 



If the tongue is injured by getting caught in a halter chain, 

 and is torn, say three-fourths off, amputate the balance. You can- 

 not get union between incised or lacerated surfaces in the mouth. 

 In examining a horse for soundness, always examine the tongue. 

 A horse with a short tongue is damaged and he cannot feed so 

 well. 



PAROTIDITIS. 



Parotiditis is the inflammation of the parotid gland. It is 

 usually acute and it usually goes on to suppuration, forming one 

 large abscess or two or more small ones. The cause may be 

 influenza or strangles, or some other blood contamination. It 

 may be due to local injury. In my experience the disease oc- 

 curs without any ascertainable cause. 



Symptoms. — The parotid gland swells and is very sore; the
