BLACK TONGUE. 



Inflammation of the Tongue. 



(Glossitis.) 



An inflammation of the tissues of the tongue. It 

 may develop under the influence of mercurial poison, or 

 as a consequence of direct injury. Croton oil and other 

 acrid matters taken into the mouth may cause it; bums, 

 blows, and the poison of insects have caused it. It may 

 be produced by diseased teeth, but sometimes occurs in 

 old horses without any apparent cause, 



SYMPTOMS:— At first the tongue has an intense 

 red appearance and is slightly swollen. This is soon fol- 

 lov.ed by so great an enlargement of the organ, that it 

 entirely fills the mouth and protrudes beyond the teeth, at 

 which time it becomes hard and black, and its surface is 

 covered by a thick secretion. There is a sensation of 

 heat in the mouth, and the swelling often causes severe 

 pain. The glands at the angle of the jaw are enlarged 

 and tender, and all movements of the tongue in chewing 

 or swallowing becomes exceedingly painful, and frequent- 

 ly impossible. Difficult breathing and inability to lie 

 dowii are sometimes caused, by the obstruction to the free 

 entrance of the air into the lungs. In extreme cases 

 death has occurred from suffocation.
