PARASITIC FUNGI AND MOULDS. 65 



subjoin the recipe has been very successful in pity- 

 riasis, and in all the infantile forms of ringworm, 

 including that which occurs in teething, and which 

 may be safely treated, in spite of prejudices to the 

 contrary : 



Turbith mineral (tri-mercuric sulphate) ... 1 to 2 grs. 

 Benzoinated lard ... ... ... 15 grs. 



This pomade is lemon-coloured ; it will assume a 

 flesh-colour by the addition of a few drops of red 

 litmus, and may be scented to the taste of the person 

 who is to make use of it. In ordinary cases of 

 pityriasis, it need only be applied every eight or 

 fifteen days. It is indispensable to wash the combs 

 and brushes in a solution of potash or ammonia, lest 

 the benefit of the treatment should be lost by re- 

 infection. In the case of true ringworm, especially in 

 adults, a much more energetic treatment is necessary, 

 for which medical advice is required.
