This at first is a tumour of the size of a pea, with little or no pain; sometimes it is of the size of a hazle nut, but does not discolour the skin, and may continue in that state for several years. When this small tumour becomes suddenly round and livid with an unequal surface, there is generally an intense shooting pain. At length it breaks through the skin, and sheds a sordid, viscid, bloody, sanious or ichorous matter, with an insupportable stench. While the cancer is small and not very painful, the best way will be to use a regular diet, and to defend it from external injuries. When it is very painful, a thin plate of lead may be laid over over it smeared with quicksilver. Let her constant drink be a decoction of Lignum Vitae, made with four ounces of the raspings, and three quarts of water boiled to two quarts. She may be purged now and then with half a dram of rhubarb mixt with five grains of calomel, and an ounce of diacodium, or twenty drops or liquid laudanum, may be given to procure sleep; when this fails, thirty drops and upwards. When the cancer is broke, the most certain way is to have it taken off before it eats too deep.
