Hear Tacitus on that subject (a). ???Vectigal quintae et vicesimae venalium mancipiorum remissum, specie magis quam vi; quia cum venditor pendere juberetur, in partem pretii emptoribus accrescebat.???* Thus, with respect to our taxes on soap, shoes, candles, and other things consumable, the purchaser thinks he is only paying the price, and never dreams that he is paying a tax.
