160 KENNEL DISEASES. 
Large warts, in this situation, which are shallow and only slightly elevated 
above the surface, can be removed by cauterizing with pure carbolic acid, the 
crystals being heated until dissolved. In using this the parts around the wart 
should first he covered with oil, to prevent the agent from reaching them. Then 
by means of a swab, consisting of a stick with a bit of cotton at the end, the 
wart should be sopped with the acid. 
The dog being held the meanwhile, that he may not lick the application, 
after fifteen or twenty minutes the parts treated should be freely bathed with 
warm water; then dried and dusted with powdered sulphur. 
Another efficient remedy is the saturated solution of the bichromate of potas- 
sium. It should be applied by means of a small swab or camel’s-hair brush 
once daily. 
The so-called one-night corn-curers owe their efficacy to salicylic acid, to 
which alcohol and ether are commonly added, and the whole incorporated in 
collodion. 
Such preparations often act quite as well on shallow warts as on corns, and 
there is certainly no reason why they should not be given a trial. 
Warts or other growths which have trunks or rise considerably from the sur- 
face should be ligated, for were they removed by scissors or knife there might 
be troublesome bleeding. 
This operation is very simple. A strong silk thread can ordinarily be used, 
but where the growths are quite large a fine elastic cord is better. The tying 
should be done as closely as possible to the surface, and the thread or cord 
drawn tightly. It will then cut through in a few days and the growth drop off. 
Or should the ligature become loosened, it ought to be tightened. 
Where there are several warts, unless they are so clustered that they must 
all be ligated together, it is advisable to treat each separately.
