Diseases of the Skin—External Parasites. 209 
these measures, result in an over-charged and over-heated 
system, and Nature, to avoid worse consequences, endeavours 
to get rid of this pressure by means of serous outpouring 
or exudation. ; 
Canine patients which have been under a prolonged course 
of bromide treatment (especially in rheumatic cases) not 
unfrequently develop a ‘‘ bromide rash” which may, if in- 
terfered with by gnawing, scratching or rubbing, be mistaken 
by an amateur or inexperienced dermatologist for eczema. 
At the same time it must not be forgotten that rheumatism 
and eczema often co-exist. Note three cases: Dandie, St. 
Bernard, and Spaniel, 3rd, 8th, and 15th August, 1888. 
Singular circumstances or phenomena in connection with 
eczematous disease occur in breeding bitches. Thus eczema 
may disappear in a canine female during lactation or suckling 
to reappear again after the puppies are weaned. Or if the © 
mother, being eczematous at the time of parturition, is 
over-stocked with milk and in plethoric or obese condition, 
the disease may manifest itself in the offspring while yet 
suckling. 
Treatment.—Saline aperients are in the first instance ad- 
visable ; when the irritation is extreme and considerable 
constitutional disturbance is manifested, a grain each of 
opium and calomel may be administered with benefit. 
With regard to local applications, the skin should never 
be washed or rubbed, in the dressing with agents, more 
than is absolutely necessary. The benzoated oxide of zinc 
ointment smeared over once or twice a day is a very 
effectual remedy. Another exceedingly useful one is:
