In the May 1933 Word Ways, Lee Sallows introduced a form of gematria he called wints (word integers), based on the use of the alphabet and a space to express numbers in base 27. (In normal gementria, A=1, B=2, etc.) His article included 3x3 and 4x4 magic squares made from wints and found by computer search. In May 1996 he presented additional 3x3 squares found by computer search. In the original article, many of the magic constants were wints. This was not true for the later set. Most are simply Euler squares which become magic for any gematria.
