dry oxide of zinc and sulphur, or 1 part of powdered alum 
to 6 of flour. Debility and wasting is overcome with 
mineral tonics and cod-liver oil, The diet should be plain, 
nutritious, but not stimulating. Daily exercise should also 
be allowed. 
I have found a liniment composed of oxide of zinc, 
odourless petroleum oil, and a little creosote or oil of tar, 
an excellent dressing for canine eczema. The addition of 
sulphur is sometimes useful—especially towards conva- 
lescence. 
Upon no consideration should an eczematous dog be

washing for at least a week after recovery. 
Chronic Eczema, though not accompanied by the same

“In chronic eczema other topical remedies are required, 
one while to relieve prurities, and another while to exert a

mercury, unguentum hydrargyri nitratis, and unguentum 
hydrargyri ammonio-chloridi. In some forms of chronic 
eczema one or other of these ointments is specific; for
