    Excerpts: “In respect to the Taxes proposed, to many of them he had no objection; but the Hon. Gentleman took credit for them in different, and even in opposite ways. Many of them, he had declared, did not affect the poor. In the article of tea, however, he believed that it was not only in general use among the poor, but he was also sorry to add, that it formed the chief part of the consumption of many of them."
    "The observation of the Right Hon. Gentleman (Mr. Fox) respecting the additional duties upon teas and wines were not founded, as, on a more deliberate view, it would be found, that the poor would get teas cheaper and better, and that wines would be obtained more pure, and less adulterated than ever.”
