Sig. : Apply as a lotion. 



The lead lotion recommended before (page 309) is also 

 excellent, but it is better to use morphia than opium, to 

 avoid staining. It is not suitable for application over a 

 large surface, for, while the dog is not readily poisoned 

 with opium, his stomach is easily disordered by this drug. 



In some cases the "black wash" (calomel and lime- 

 water) is valuable. 



Prepared chalk in the form of ointment or wash, with 

 or without lime-water, has also given good results. 



By allowing water to stand over tar till it tastes strongly 

 of this substance, a lotion suitable for the red unbroken 

 skin may be made. For the eczema that attacks the face, 

 especially the eyelids and eyebrows, some form of mercu- 

 rial ointment may be demanded (see page 310). The liquor 

 plumbi subacetatis may be combined with the tar-water. 



Soothing ointments may be made of sulphur, ox- 

 ide of zinc, borax, lead salts (acetate and subacetate), etc. 

 These ointments as officinal preparations may be pur- 

 chased ready-made. It may be wise to dilute them at 

 times, or add alkalies, carbolic acid, or opiates. 



The unguentum zinci (officinal) is a most valuable 

 ointment for soothing and drying; but when parasitic 

 disease is suspected the sulphur ointment should take its 

 place.
