    […] an incensed political surgeon, who is not in much renown for his mercy, upon great provocations: who, without waiting for his death, will flay and dissect him alive; and to the view of mankind lay open all the disordered cells of his brain, the venom of his tongue, the corruption of his heart, and spots and flatuses of his spleen: and all this for threepence.
