632 Cf SCALD-HEAD OK PORHIGO SCUTULATA. 
the ears, and above and between the eyes, and below the 
eye and ear on either side, covered with a scab, which pre¬ 
sented a greenish-brown appearance, seeming to have been 
dressed with some ointment of a green colour. Gave some 
Pulv. Ipecac. Comp. 10 grs. daily, to endeavour to remove 
the “sniffles,” which, however, I am inclined to attribute to 
the sore on the forehead. 
16th.—Met Dr. T-, who examined the dog, and con¬ 
sidered it to be suffering from “scald head,” of which he 
had a case lately at the Barracks. Brought dog home with 
me. The eruption is evidently not due to traumatic cause, 
for on the edges of the patch are fresh eruptions ; in one place 
a thin line of pus is oozing through the scab. Where the 
eruption is just breaking out the cutis is raised as by a blis¬ 
ter. It is then soon removed by the scratching of the dog. 
The papillated structure of the dermis is thus exposed, and 
at first emits a sero-sanguineous matter ; this is followed by 
oozing of serum, which dries up, forming a greenish powder, 
which I had on the 14th mistaken for ointment. A scab of 
about one eighth of an inch in thickness then forms. Scales 
rubbed off forehead. 
17th.—-The disease is rapidly extending backwards, down¬ 
wards, and forwards between the eyes, involving the eyelids. 
14 01. Jec. Ass. 20 parts; 01. Tereb. 1 part; Amm. Tort. 1 
part; mix to form a liniment. Dressed dog all over except 
eyes with this soap, washing her well, which pained her 
much. Fed principally on vegetable diet. 
18th.—Slight signs of hair growing on the bald surface. 
Altogether looks much better, and in two or three places 
where the eruption was commencing it seems to have been 
checked. 19th.—Right eye completely closed by discharge. 
Remove this and dress the eyelid with ointment. 
21st.—Disease does not seem to be spreading, and scabs 
from the places most recently affected come away readily. 
Dog seems improved in condition. In a short time the 
patient completely recovered. 
I regret that I was not in a position when this case came 
under my notice to examine the morbid conditions micro¬ 
scopically, nor to experiment as to the transmissibility of 
the affection. I simply give the case as it occurred. In 
the treatment I was guided rather by convenience than by 
pathological reasoning. But cure of a progressing skin dis¬ 
ease of the dog, in less than a week, in fact, by a single 
dressing, was very satisfactory to me.
