The construction of palindromes is an extremely old entertainment among word lovers and requires no introduction. Much newer are charade sentences which were introduced by Howard Bergerson in Word Ways and most recently discussed there by Hearst Sill Rogers in the May 1977 issue. In the February 1977 Word Ways there appeared a series of "double" palindromes by the writer of this article. Some readers have doubtless recognized the double palindrome as being merely a pair of charade sentences composed with the additional constraint of being palindromic or, more simply, of being palindromic charade sentences. I believe this to be a new form of amusement worth noting more fully.
