There is one way by which a strolling player may be ever secure of success; that is, in our theatrical way of expressing it, to make a great deal of the character. To speak and act as in common life is not playing, nor is it what people come to see; natural speaking, like sweet wine, runs glibly over the palate and scarcely leaves any taste behind it; but being high in a part resembles vinegar, which grates upon the taste, and one feels it while he is drinking.
