In either case the affected parts are more or less depilated, red 

 if oil uiipigmeiited skin, grayish and scabby or scurfy if on the 

 darker. At times, after recovery, the patch remains devoid of 

 pigment and hairs growing from it are white. 



Treatment. It is usually desirable to clear out the prima vise 

 by aloes or Glauber salts, to resort to a carefully regulated, non- 

 heating diet, to clean the skin of all concretions from sweat or 

 otherwise, to give pure air and shade and to protect the animal 

 from active exertion, profuse sweating and friction by har- 

 ness or otherwise. In the early stages benefit will often come 

 from the use of alkalies, especially sodium bicarbonate. Locally 

 an inunction with vaseline to soften crusts, and the subsequent 

 removal of these with tepid water, may be followed by some sooth- 

 ing or astringent application, always bearing in mind that what is 

 soothing to one skin is irritant to another. Dusting powders 

 (starch, lycopodion, magnesium carbonate, oxide of zinc, calamine, 

 bismuth) will often do good ; soothing lotions or liniments (lead 

 acetate with laudanum, lime water and olive oil ; sodium bicarbon- 

 ate in well boiled gruel of oatmeal or marsh mallow ; zinc oxide or 

 sulphate in water or glycerine or as ointment in vaseline, etc, 

 etc). In chronic .stages with much squama and pruritus tar water 

 or ointment ; a lotion of tar and alcohol ; creolin hjtion ; chloral 

 lotion ; or other stimulant application may be used. 



CHRONIC ECZEMA OF THE HEAD IN SOEIPEDS.* 



Affects face, eyelids, cheeks. Symptoms : papules, vesicles, dry, rigid 

 skin, scurf, glistening, shedding hairs. Treatment : as in eczema ; anti- 

 septics. 



The cheeks and forehead are the most liable to suffer in this af- 

 fection, yet the eyelids and the parts below the inner canthus 

 may participate in connection with the escape of tears and the dis- 

 ease of the lachrymal sac or ducts. It has been seen in the 

 young when .strangles had merged into skin eruption, but also in 

 the aged and independently of that affection.
