This is to be applied one day ; washed off the next ; and then the dressing 
repeated until the dog has been dressed three times, and washed thrice ; 
after which the ointment may be discontinued ; but again had recourse to 
if the animal exhibits the slightest signs of uneasiness ; when the entire 
process may be gone through once more. Mercurial ointments are the 
most certain remedies for this disorder ; but then they are not safe, and 
should always be avoided where the dog is concerned. 
“ The second kind of mange is where hair partially falls off ; and this 
kind of disorder is well marked by bare patches of small dimensions, show- 
ing themselves on the point of the elbow and any part which is prominent, 
and which the animal might be supposed to have rubbed as he laid in his 
kennel. The patches are small and free from hair ; but at the same time 
the skin exposed is rough, scaly, thickened, and corrugated. The itching is 
intense; but it does not particularly affect the exposed part; it rather 
seems to reside in those portions of the body which are well covered with 
hair. 
“ For this form of .disease the cure begins with tonic medicine; and after 
this has been administered a week or a fortnight, as the strength may 
appear to require restoration, it is suddenly left off ; and liquor arsenicalis, 
in gradually increasing doses, is administered. If it be a little dog, let 
the first day’s dose consist of half-a-drop each time ; and if for a large 
animal, of two drops at each dose ; three doses in either case to be given 
in the course of the day. In the former case, the quantity of arsenicalis is 
to be increased half-a-drop each day, and in the latter instance one drop 
daily is to be the advance ; the quantity in both cases to be distributed 
over three doses, one to be given in the morning, one at noon, and the last 
at night. 
“ The medicine is to be kept on increasing each day, until the dog loathes 
his food ; has a running from the eyes ; a scarlet conjunctiva ; or exhibits 
some symptom that denotes the physic has hold of his system ; when the 
arsenicalis is to be discontinued for three days, and then steadily persevered 
with, at the dose which preceded the derangement. Thus, supposing it 
requires three and a half drops to throw the small dog off his appetite, the 
quantity to resume with will in that case be three drops. 
“ There is no power I possess which can predicate the quantity of the 
liquor arsenicalis which an animal will bear ; its effects on different creatures 
of the same species are so various, that what one can gorge with impunity 
would kill his companion. On this account no fixed quantity of the medicine 
can be recommended ; but the practitioner must be satisfied to watch the 
symptoms induced, and be content to be guided by these. So soon as the 
physiological symptom is beheld, the good results of the medicine may be 
anticipated ; and no compound in the pharmacopoeia works with greater 
certainty. The disease will begin to decline ; and in a month, six weeks, or 
two months at furthest, will be thoroughly eradicated. In the course of 
that period, however, it may be as well to give Nature a jolt every now and 
then, by occasionally increasing the dose, being always prepared to diminish 
it on the symptoms giving the slightest hint that it is prudent so to do. 
The arsenicalis should be used simply diluted with water ; and during the 
period occupied by the cure, no other medicine whatever will be required. 
“ Here I may for the present conclude my imperfect account of mange ; 
again insisting that in every form of the disorder the food is to consist of
