Idquor Arsenicalis. — It is sometimes necessary to apply a 

 preparation of Arsenic for the cure of this malady; and one 

 of the most favourable for this purpose is the Liquor Arsenicalis. 

 It may be applied as I have directed the Tincture of Iodine to

Upon opening the tumour, a grey-coloured mucus-Uke fluid 

 escaped, and this exposed to view a quantity of long hair, a 

 portion of which was of a black colour, and another portion
