This treatment must be persevered with for a month, 

 a camomile purge then given, and the arsenical 

 mixture recommenced in a week or ten days' time. 

 The idea of leaving off the arsenic for the period

 gogue laxative, is to expel any traces of arsenic that 

 may have accumulated in the system. Feed liberally 

 on raw meat, keep the kennel clean, change the 

 bedding frequently, and place the animal under the 

 best conditions obtainable, not, of course, neglecting 

 exercise, which has very often a good deal to do with 

 the production of eczema. The moist forms of 

 eczema are benefited by dusting the surface with 

 some protective powder, of an antiseptic or astrin- 

 gent nature, such as one part of powdered boracic 

 acid to three parts of powdered starch; lotions are 

 also useful for a similar purpose, such as an ounce 

 of creosote to eight or ten ounces of methylated 

 spirits of wine, freely wetting the surface with it. 

 In some cases baths do good, whereas in others they 

 are absolutely harmful. Chronic forms of eczema 

 are recurrent, and prolonged treatment has to be 

 indulged in before a cure can be anticipated.
