296 KENNEL DISEASES. 
requires special treatment, the preparation in use might be stopped for a short 
time and the following be applied sparingly : 
Carbolic acid, one drachm; oxide of zinc ointment, two ounces. 
Or the ointment composed of morphine, camphor and oxide of zinc oint- 
ment, recommended in the foregoing, might be tried. 
The mixture of whale-oil and chloroform, previously advised, could be 
used after the surface was free of crusts; but since it is thin and very volatile, 
it would be advisable to thicken it to the consistency of ointments. For this 
purpose wax should be chosen, and the proportion of it be about one-fourth. 
Still another ointment that usually controls itching, especially in cases of 
eczema of long standing, is the following: 
Oxide of zinc ointment and compound ointment of subacetate of lead, of 
each half an ounce; chloral hydrate and powdered camphor, of each fifteen 
grains; powdered sulphur, one drachm; pineoline, two ounces. This to be 
rubbed in well, morning and night. 
Strangely, perhaps, some cases of chronic eczema have done well under 
the application of male fern after they have resisted other remedies. It is used 
as follows: 
Alcoholic tincture of male fern, one ounce; alcohol, half an ounce; tincture 
of myrrh, one drachm ; balsam Peru, three drachms. 
This is very strong, and the only cases in which it should be tried are those 
in which the eruption is of small extent, very dry form, and the affected sur- 
face is covered with crusts. The latter should first be removed by washing, 
green soap or ordinary soft soap being used, and the mixture then be lightly 
rubbed in. It irritates considerably at first, but, as a rule, only a little, if any, 
after a few days. If likely to have good effect, a gain would be noticeable in 
the course of a week. 
In occasional cases, and especially of dogs kept in houses, the tarry prepa- 
rations, and indeed all ointments, would be decidedly objectionable, therefore 
lotions must be used, and the following is recommended : 
Carbolic acid, two drachms; alcohol and glycerin, each one ounce; water, 
six ounces. This may be applied with brush or sponge: and it is generally 
quite serviceable in the scaly form of eczema. 
A more agreeable preparation for use on house pets suriering from dry 
forms of eczema is composed as follows: 
Compound tincture of benzoin, one drachm; alcohol, one ounce and one- 
half; water, three drachms; glycerin, six drachms. It should be applied to 
the affected surfaces, twice daily, after the same have been washed with soap 
and water, and carefully dried. 
Where the affected dog is kept in kennels, and his owner cannot devote 
much time to him and apply ointments as often as required, it would be well 
for him to give clear balsam of Peru a trial. It is thick, like syrup or honey,
