Enquire within upon everything by Robert Kemp Philp

This is a riddle (_logos_, a word, and _griphos_, a riddle) in which a word is made to undergo several changes. These changes are brought about by the addition, subtraction, omission, or substitution of a letter or letters. The following, by the late Lord Macaulay, is an excellent example: "Cut off my head, how singular I act: Cut off my tail, and plural I appear. Cut off my head and tail--most curious fact, Although my middle's left, there's nothing there! What is my head cut off?--a sounding sea! What is my tail cut off?--a flowing river! Amid their mingling deaths I fearless play Parent of softest sounds, though mute for ever!" The answer is _cod_. Cut off its head and it is _od_ (odd, singular); its tail, and it is Co., plural, for company; head and tail, and it is o, nothing. Its head is a sounding C (sea), its tail a flowing D (river Dee), and amid their depths the cod may fearless play, parent of softest _sounds_ yet mute for ever.
