 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-like fluid

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