of water, and apply two or three times daily, so 
as to touch every portion of the diseased surface. 
Tincture chloride of iron, full strength, applied to 
it is also useful. Nitrate of silver, either in solu- 
tion or pencil, is also good. When there is much 
fetor the mouth should be washed with a solution 
of carbolic acid, one to fifty. The little animal 
should be supported by brandy and eggs, one to 
two grains of quinine should also be given twice 
a day. 
BLACK TEETH. 
There has been a great deal said and written on 
this subject, but the great majority of the profes- 
sion at the present day consider that black teeth 
is not a disease which is capable of causing death. 
I have studied black teeth and have never been 
able to connect it with any of the diseases affect- 
ing the pig, and in the majority of cases it seems 
‘to do no harm to the animal’s health. I have no 
doubt, however, that pigs suffer as well as other 
animals from tooth ache, but I have never seen any 
cases where I could detect it. Iam not able to ac- 
count for the cause of black teeth unless it be nat- 
ural for some hogs to have them. If it should be 
discovered that a hog has a decayed tooth and is 
apparently suffering from it, by all means have it 
removed, which can easily be done with a pair of 
wolf teeth forceps. I can advise swine breeders 
not to trouble themselves if they should notice 
some of their pigs having discolored teeth.
