first. Hence the following general rule: A comic effect is always obtainable by transposing the natural expression of an idea into another key.
The means of transposition are so many and varied, language affords so rich a continuity of themes and the comic is here capable of passing through so great a number of stages, from the most insipid buffoonery up to the loftiest forms of humour and irony, that we shall forego the attempt to make out a complete list. Having stated the rule, we will simply, here and there, verify its main applications.
