best means of cure is dipping in an arsenical solution. Mr. Morton 
recommends an arsenite of potash, made up as follows: 
Arsenic, J lb. 
Carb. Potass., i lb. 
Water, 12 gallons. 
Care should be taken in dipping not to allow the animal to go 
overhead. 
We find dogs also affected with this disorder, in two or 
three forms. We have what is termed foul mange, constitutional 
in its nature, being truly a disease of the blood, and requiring a 
complete change before it can become eradicated. 
It is doubtful whether this form is contagious, but it certainly is 
hereditary. A short time ago I had a bitch of the St. Bernard’s 
breed under my care, suffering from this complaint. She got well, 
being in pup at the time. I watched for results. The pups did 
well until about two months old, when the disease made its appear¬ 
ance in them, and they all died, one after the other. The bitch still 
remains apparently healthy. 
The treatment of this disorder must commence by the adminis¬ 
tration of an aperient, followed up by doses of Liq. Arsenicalis, in 
the proportion of one drop to each four pounds’ weight of the 
animal, three times a day. Keep on a vegetable diet, and dress the 
skin with sulphur ointment. The other form of the disease, depend¬ 
ing on the presence of a parasite, is principally seen in animals that 
have been badly cared for. It is highly contagious, as in other 
animals. The treatment should be an ointment composed of iodide of 
mercury 2^ drachms, lard 2 ounces, used every other day, with 
proper attention as to food and cleanliness. There is another form of 
this affection, said to arise from a vegetable parasite, but, not having 
had any experience of it, I cannot speak much about it. There is 
yet another form of this affection seen in dogs, viz.—red mange. 
Here we have a disease said not to depend on the presence of a 
parasite, but on an affection of the hair-bulbs, causing a change in 
the colouring matter of the hair. For instance, if the animal be a 
white one, the hair will appear of a pale brick-dust colour, almost as 
if the dog had been sprinkled over with this material. House-kept 
and highly fed animals are most frequently the subject of this 
disorder. The disease first shows itself at the elbows and in¬ 
side the arms, then on the front and inside the thighs, next on 
the buttocks, and finally on the back, which is only attacked when 
the disease has existed for some months. The general health does not 
seem to suffer much, nor yet is the disease thought to be contagious. 
The treatment consists in lowering the diet, administration of 
aperients, following these up by the addition of green vegetables in 
the food, at the same time dressing daily with an ointment of iodide 
of mercury li drachms, turpentine oz., mixed with IJ oz. of 
lard. 
Dogs are troubled a good deal with inflammatory action of the 
skin from the presence of fleas, lice, and ticks, which may be got 
rid of by washing well with carbonate of soda and soft soap. Ticks
