In the original 'The Sabian Symbols in Astrology' Marc Edmund Jones gives comment on every change he made in the handwritten text on the cards (p.136). He had written the words of Elsie Wheeler down very quickly, so here and there they were hard to read. He also made some changes, but small ones.
  I am very grateful he gives such a detailed account of every change. I have changed everything back, because I think one cannot change anything in a symbol. Sometimes errors also have a meaning, and a way of saying something can give another color, even if it is not correct English. I even made airplane to aeroplane again, which is not important, but after all in 1925 it was written that way.

  Minor matters of punctuation and some corrections in spelling need no comment. Abbreviations have been spelled out, as in the case of gymnasium for gym and auto-mobile for auto. Airplane is used for aeroplane (Gemini10, Libra 27). In a few cases the pencil is impossible to decipher with certainty, so that Capricorn 6 could be two instead of ten logs. Gem was read for germ (Cancer 17) and parts for paths (Libra 15) in preparing the 1931 interpretations. A serpent is coiling, not circling (Aries 14). Side comments have been ignored. Thus the Tuileries card had Paris on the margin (Gemini 3). Taurus 19 was marked tangible, and this idea has been incorporated in the description. In Sagittarius 17 the word sunrise is inserted, since a notation that it was early a.m. had been jotted down at the edge. In Cancer 10 the diamond is said to be not quite cut instead of not quite carved, as was written on the card. In Leo 6 the word flapper is re-placed with the phrase up-to-date girl, and in Gemini 16 the suffragist is said to be haranguing rather than orating, as the pencil notes have it. Chocolate is changed to colored in Virgo 4.
  There is a great mystery, which may be part of what occultists know as the necessary twist in any series of relations of spiritual import, since the cards for Libra 18 and 19 were first in reverse of their present order, and then the descriptions were scratched and repenciled as they are found in all the various versions of the Sabian degrees, and as indeed they seem correctly placed. There is neither record nor recollection of what happened in this connection, whether originally in San Diego’s Balboa Park or when the first typed documents were made by Marc Edmund Jones.
