244 THE PRACTICE OF VETERINARY MEDICINE. 



undergoes complete destruction. The fourth and most 

 severe form of burn is that in which the skin, and the 

 tissues beneath the skin, suffer destruction, and the circula- 

 tion of the part ceases. This description of burn, when 

 extensive, which it usually is, as a general thing causes 

 death. 



Symptoms. — If the burn be very severe there are usually 

 well-marked rigours, followed by great depression; the 

 patient shows signs of being in great pain, etc. 



Treatment. — As soon as possible after the burn has been 

 received the air should be rigidly excluded. Several plans 

 are recommended by which the air may be excluded from 

 the injured parts ; probably the best of all being an appli- 

 cation of carron-oil, which is composed of aqua calcis et 

 ol. lini, pars equale. It is called carron-oil because it was 

 used first at the Carron Iron Works in Scotland, where 

 people frequently suffered from burns ; its use was attended 

 with better effect than that of any other application, and 

 finally became general. If there is much depression, stimu- 

 lants should be administered ; and if the animal shows 

 signs of much pain, the use of opiates internally, and 

 sedative or anodyne applications — as Goulard's solution 

 plumbi diacetas, opii, etc. — externally, will be of benefit. 

 Large sloughs may occur, particularly if the burn be in 

 connection with the muscles of the haunch, and yet a pretty 

 good recovery may result. Where stables burn down, and 

 the flame has been inhaled, it almost invariably results in 

 death.

 quacks the condition is usually termed sweeney. The ex-
