36 DISEASES OT DOSS. 



seeks the slaughter-house. Of course, a bum or scald may be the 

 result of pure accident, and of tenest happens to that class technically 

 termed " cinder- worriers." The best application to either bum or 

 scald is the preparation known as Carron oil, which is made by 

 mixing equal parts of linseed oil and lime water. It should be 

 applied freely, and as soon after the accident as possible. As a 

 useful remedy it should be kept in every house, but especially in 

 every country house. In such cases the dog should he kept quiet, 

 receive plain food, and be given a mild aperient. A bum or scald, if 

 severe, often gives a violent shock to the system, and symptoms of 

 Ulness arising from it must be observed and treated according to 

 circumstances. Carron oil is best applied direct to the wound alone, 

 and then immediately thickly covered with cotton-wool to exclude 

 the air from the bladders formed. The dressing should be repeated 

 when necessary, care being taken that no hairs or other irritating 

 substances are left on the sore places. 



CALCUILX. — The dog is more frequently the subject ot Calculi 

 (Stone) than is generally supposed. Their locality varies ; they 

 may exist in the biliary ducts, the bladder, the kidneys, or in 

 the urethra (the passage of the penis). 



In Biliary calculi, those stones situated in the biliary ducts, pro- 

 viding they are sufficiently small to pass the duct are not of great 

 moment — in fact, upon post-mortem one often discovers their exist- 

 ence, while during life no inconvenience or pain was noticed^but 

 should these stones be too large to pass the ducts, they are very 

 painful and a most fmitful cause of jaundice. The bile, which in 

 health passes through these ducta, becomes completely impeded in 

 its progress, and is re-absorbed by the blood-vessels entering the 

 general system, and jaundice is established. The symptoms of 

 biliary calculi when not completely blocking the ducts, are excessive 

 sickness and constipation, with pain in the abdomen. The treat- 

 ment should consist in allaying the pain, when the stone will 

 frequently pass in a natural way. To accomplish this object give 

 S to 30 drops of tincture of opium, every four hours, in a little water, 

 and a soap and water enema night and morning to relieve the bowels, 

 opium having a tendency to constipate. 



Cystic calculi is the name given to stones found in the bladder ; 

 it is generally supposed that their existence is extremely rare, but 

 such is certainly not the case. A single large stone is not frequently 

 seen, but a nmnber of small ones, especially in old dogs, is not at all
