LACERATIONS OF THE FIRST THREE TRACHEAL CARTILAGINOUS 
RINGS MISTAKEN FOR AN ATTACK OF PHARYNGO-LARYNGITIS. 
By Mr. Brtj. 
In this case a mule hitched to a cart fell down and was 
severely wounded in the upper part of the neck in consequence 
of the breaking of one of the shafts of the vehicle. The man, 
ner in which the injury occurred was only known after the 
fatal termination of the case became imminent, the facts not 
being reported until the subsequent development of the symp¬ 
toms, whe’n the patient became seriously sick. When first 
seen there was tumefaction of the right parotid region, and 
the food returned with the discharge from the nostrils and 
was coughed through the mouth whenever he was fed with 
the hay or bran mashes which constituted his fodder. The 
general appearance of the patient was good, and there was 
no disturbance either of the respiration or circulation. A 
local embrocation was applied to the parotid swelling, and 
the animal was placed under observation. Three days later 
there was an appearance of fluctuation in the parotid, which, 
upon being punctured, discharged, instead of pus, a small 
amount of blood mixed with a few bubbles of air, and this 
condition continued until the death of the animal, which occur¬ 
red seven days after the injury. At the post-mortem the first 
ring ol the trachea was found to be fractured in its entire 
extent, and the third and fourth cartilages were separated, the 
fibrous tissue which unites them having been torn by the blunt 
end of the shaft of the cart. The tracheal mucous membrane 
was slightly congested .—Revue Veter inair e.
